Remarks

Using the Provider with Secure Hypertext Transfer Protocol (S-HTTP):

Sending HTTP and SOAP requests using S-HTTP requires additional setup.

Install the server authentication certificate on the computer that hosts your Web site.

Install the client authentication certificate on the client computer for both the MPFServiceAcct and local
user accounts. This ensures that the provider will always have permission to access this certificate.

Verify that both the server and client computers have the Certification Authority (CA) certificate installed
in the Trusted Root Certification Authorities/Certificates directory.

When designing the XML schema for the request, specify the certificateName and certificateStore nodes.

Customizing Registry Settings

Several Microsoft. Windows. registry values allow customization of the HTTP and SOAP Provider. These values are located in \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Provisioning\Providers\MPFSoapProv.

Value Description

CleanupSleepTime Number of milliseconds the cleanup thread sleeps before browsing the list of connections to clean up. Cleaning up connections locks out all threads from connections, which is why this should not be done too frequently.
Default Value: 120,000
Minimum Value: 0
Maximum Value: 4,294,967,295 (infinite)

CompletionThreads Number of completion threads to specify when initializing the provider's HTTP engine.
Default Value: 0 (auto-adjusts four threads per processor)
Minimum Value: 0
Maximum Value: 4,294,967,295 (infinite)

If either CompletionThreads or ConnectionThreads is zero, set both as follows:
CompletionThreads = 4 * number of CPUs
ConnectionThreads = ( number of CPUs + 1 ) / 2

ConnectionExclusionInterval Number of milliseconds to wait before re-attempting a failed connection with a server.
Default Value: 0 (no waiting)
Minimum Value: 0
Maximum Value: 345,600,000
Out-of-Range Action: Error

Whenever the provider cannot successfully send requests to a server, it immediately places the server on a bad server list and returns an error to indicate that the remote service is currently unavailable. At periodic intervals (for example, every 50,000 milliseconds), the provider re-attempts the connection.

This setting minimizes unnecessary resource consumption of network bandwidth, CPU cycles, and other system resources during a failure. It also enables the provider to generate a more immediate error to alert the caller that the server is not available.

Connection unavailable time can be specified either in the registry or in individual requests (in the connectionExclusionInterval node). Requests use the default registry value whenever they do not have a value for connectionExclusionInterval.

Note: The provider adds a server to the bad server list only for the provisioning engine that executes the provider. Other engines include the server on their bad server lists only if they also experience a failure.

ConnectionThreads Number of connection threads to specify when initializing the provider's HTTP engine.
Default Value: 0 (auto-adjusts one thread for every two processors)
Minimum Value: 0
Maximum Value: 4,294,967,295 (infinite)

If either ConnectionThreads or CompletionThreads is zero, set both as follows:
ConnectionThreads = ( number of CPUs + 1 ) / 2
CompletionThreads = 4 * number of CPUs

ConnectionTimeout Number of milliseconds to waith for a server connection to complete before terminating and returning an error. The server connection can be shared and left open for multiple requests.
Default Value: 30,000
Minimum Value: 1
Maximum Value: 4,294,967,295 (infinite)
Out-of-Range Action: Error if value is zero

FailureTriggerForExclusionList Number of consecutive failures that must occur before a URL is included on a bad server list.
Default Value: 5
Minimum Value: 0
Maximum Value: 4,294,967,295 (full range of a DWORD)

LogEvents Identifies whether the provider logs transaction failures to the event log.
Default Value: 1 (logs events)
Minimum Value: 0 (disables logging)
Maximum Value: 1
Out-of-Range Action: Error

MaxConnections Number of connections a connection pool can contain. An attempt to generate additional connections will result in an error.
Default Value: 150
Minimum Value: MinConnections value
Maximum Value: 4,294,967,295
Out-of-Range Action: Error

MinConnections Number of connections a connection pool starts out with.
Default Value: 3
Minimum Value: 0
Maximum Value: 4,096
Out-of-Range Action: Error

RetrySleepTime Number of milliseconds to wait before retrying after receiving an erroneous response.
Default Value: 1,000
Minimum Value: 0
Maximum Value: 600,000
Out-of-Range Action: Error

ServerTTL Number of milliseconds to allow a server to remain inactive. If the cleanup thread is cleaning up and the server is inactive longer than this value, its pool of connections will be disconnected and deleted.
Default Value: 60,000
Minimum Value: 0
Maximum Value: 4,294,967,295

UseConnectionPool Boolean that specifies whether the provider uses connection pooling.
0: Connection pooling is disabled. Every request creates and destroys its own connection.

1 (default): A connection pool is created for each unique connection string, and connection objects are created and added to the pool as needed to satisfy the pool's minimum size requirement (as specified by the MinConnections setting).

UseProxy Boolean that specifies whether to use a proxy server.
0 (default): Do not use proxy server.

1: Use proxy server.

If you have difficulties getting the HTTP and SOAP Provider to connect to a remote server (for example, you keep getting DNS errors) and you have a proxy server on the network, change UseProxy to 1. Afterwards, shut down and restart the MPF provisioning engine in Administrative Tools, Component Services.

By default, the HTTP and SOAP Provider derives its proxy handling from the Internet Explorer proxy server settings defined for the MPFServiceAcct logon account. (In Internet Explorer, on the Tools menu, click Internet Options, click Connections, click LAN Settings, and then click Proxy server.) However, for security reasons, an Active Directory security policy might prohibit MPFServiceAcct from local logons. There are two ways to work around this situation.

First, you can disable the existing proxy setting and set the new proxy information directly into the Windows registry.

Open Regedt32.exe.

Add the following key/value of type REG_DWORD to the subkey \HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings.

ProxySettingsPerUser = 0

Update the following subkey values for
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings

ProxyEnable = 1
ProxyServer = server:port #
ProxyOverride = <local>

Alternatively, you can temporarily deactivate the security policy for MPFServiceAcct, then log on to update the proxy setting in Internet Explorer. Afterward, you would log off and re-establish the security policy for MPFServiceAcct.

Note The provider currently only supports a ProxyOverride value of "<local>". Other semicolon-delimited server names in the list are ignored.

Troubleshooting

The following table lists common problems and solutions.

Problem Solution

Proxy or DNS errors Consider setting the UseProxy registry key.

Server timeouts If a server application runs too slowly, you can review NetMon and PerfMon (for MPF performance counters such as Latency) or attach a debugger to the server process. If the timeout only occurs under stress, try increasing the NumThreads value for the registry key \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSOAP\SOAPISAP on the server until there are enough threads to support the required load.

Invalid SSL certificate for WSDL procedures Use Internet Explorer to verify that the URL for the wsdlFile element works, then verify the service port address returned in the WSDL file. All three must use S-HTTP, and all three must have exactly the same target server name. The typical error codes are 0x80090322 and 0x80090325.

15-second delay in the first request to a server This problem can be caused by a DNS lookup timeout before a successful NetBIOS name lookup. Fix the DNS problem, use the IP address, or try the full DNS name.

Error 0x800401F3 This error occurs when a wsmlFile node is specified, but the object specified by the WSML file's ProgId is not installed on the same machine as the provider. To prevent this problem, either omit wsmlFile or install the object.

ServerTTL	Number of milliseconds to allow a server to remain inactive. If the cleanup thread is cleaning up and the server is inactive longer than this value, its pool of connections will be disconnected and deleted. Default Value: 60,000 Minimum Value: 0 Maximum Value: 4,294,967,295
UseConnectionPool	Boolean that specifies whether the provider uses connection pooling. 0: Connection pooling is disabled. Every request creates and destroys its own connection. 1 (default): A connection pool is created for each unique connection string, and connection objects are created and added to the pool as needed to satisfy the pool's minimum size requirement (as specified by the MinConnections setting).
UseProxy	Boolean that specifies whether to use a proxy server. 0 (default): Do not use proxy server. 1: Use proxy server. If you have difficulties getting the HTTP and SOAP Provider to connect to a remote server (for example, you keep getting DNS errors) and you have a proxy server on the network, change UseProxy to 1. Afterwards, shut down and restart the MPF provisioning engine in Administrative Tools, Component Services. By default, the HTTP and SOAP Provider derives its proxy handling from the Internet Explorer proxy server settings defined for the MPFServiceAcct logon account. (In Internet Explorer, on the Tools menu, click Internet Options, click Connections, click LAN Settings, and then click Proxy server.) However, for security reasons, an Active Directory security policy might prohibit MPFServiceAcct from local logons. There are two ways to work around this situation. First, you can disable the existing proxy setting and set the new proxy information directly into the Windows registry. Open Regedt32.exe. Add the following key/value of type REG_DWORD to the subkey \HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings. ProxySettingsPerUser = 0 Update the following subkey values for \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings ProxyEnable = 1 ProxyServer = server:port # ProxyOverride = <local> Alternatively, you can temporarily deactivate the security policy for MPFServiceAcct, then log on to update the proxy setting in Internet Explorer. Afterward, you would log off and re-establish the security policy for MPFServiceAcct. Note The provider currently only supports a ProxyOverride value of "<local>". Other semicolon-delimited server names in the list are ignored.

Problem	Solution
Proxy or DNS errors	Consider setting the UseProxy registry key.
Server timeouts	If a server application runs too slowly, you can review NetMon and PerfMon (for MPF performance counters such as Latency) or attach a debugger to the server process. If the timeout only occurs under stress, try increasing the NumThreads value for the registry key \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSOAP\SOAPISAP on the server until there are enough threads to support the required load.
Invalid SSL certificate for WSDL procedures	Use Internet Explorer to verify that the URL for the wsdlFile element works, then verify the service port address returned in the WSDL file. All three must use S-HTTP, and all three must have exactly the same target server name. The typical error codes are 0x80090322 and 0x80090325.
15-second delay in the first request to a server	This problem can be caused by a DNS lookup timeout before a successful NetBIOS name lookup. Fix the DNS problem, use the IP address, or try the full DNS name.
Error 0x800401F3	This error occurs when a wsmlFile node is specified, but the object specified by the WSML file's ProgId is not installed on the same machine as the provider. To prevent this problem, either omit wsmlFile or install the object.
