After installation of TFS beta3 and Sharepoint 2.0SP1 I have problems with accessing Sharepoint. During installation there were no problems, as I have reinstalled twice, I especially looked at the sharepoint part. At the end of sharepoint installation the "Configure Administrative..." opens at it should.
After installation of TFS, I try to access the Sharepoint Central Administration from Administrative tools. I'm logged in as TFSSETUP (with administrator privileges). I get a log in window where I write TFSSETUP as user and password. I get the same log in window three times. Then the following appear:

Problem with SharePoint when creating a project in TFS beta3

Hi Elisabet,
I solved it by adding the the TFSSERVICE to the builtin administrators group nevertheless. I noticed that this was a change between Beta 2 and 3. This probably wasn't tested thouroughly.
From a security point of view it is not advisable, but at least you'll be able to install it TFS. You could also start tweaking by giving this account more rights on the underlaying directories of SharePoint I guess.

I can create a project and manage my users both in Sharepoint and SQL.

We are aware of the issue and will have it fixed for RTM.
Thanks

I have tried to edit the web.config in the sharepoint root (central administration, setting customErrors mode="Off" ). Then I see the following errors instead of the Runtime error above.
Server Error in '/' Application.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
