Exploding TFS Groups For User Investigation

When users are using Team Explorer and viewing the group membership for a particular project (Team Project Settings -> Group Membership) it’s pretty easy because explicit users and groups are listed. However, this becomes a problem when you want to view all the users of that particular group. This is very, very evident when the groups are chained, i.e. Group X contains Group Y, which contains Group z, and so forth. This becomes an issue because viewing the security information for a particular security group becomes very limited.

Fortunately, to get around this limitation you can use the TfsSecurity tool, specifically the TfsSecurity /imx command, to get the direct members of the specified group.

It is important to remember that TfsSecurity.exe comes from Team Explorer, not the Visual Studio shell.

TFS Proxy Server Unexpected Shutdowns

TFS Proxy Servers are essential for my current client’s TFSenvironment because they allow the disparate SharePoint development environment to experience improved network performance by caching copies of VC files. Since this particular environment is geo-distributed, this is a necessary architectural requirement in order to maintain appropriate developer efficiency.

Recently, a strange issue was occurring with my clients geo-environment where the proxy servers would start shutting down repetitively. The exact error you may run into is:

The VSTF Proxy Server stopped at [server]. The application is being shutdown for the following reason: HostingEnvironment. For more information …..”

Now this can happen for a variety of reasons, but first thing is you should enable proxy server tracing to get some more relevant error information by opening the web.config in the VersionControlProxy folder by setting the traceDirectoryName to a familiar storage location and changing traceWriter to true. For this particular error, one of the error returns can be:

Detailed Message: TF53002: Unable to obtain registration data for application VersionControl.
TF30055: Visual Studio could not find or read the Team Foundation Server server name in the configuration file. Contact your Team Foundation Server administrator. (type VstfNotConfiguredException)

If you get this error, the TfsNameUrl appsetting is not configured in the web.config file for the proxy server. Locate the:
[xml]

[/xml]

element and change it. After, check your IIS app pool setting and check that the recycle interval or memory limit. After, you should be good to go!
