Asp – Team Foundation Server Port 8080 ASMX Access Issue

By default, only the "Team Foundation Administrators" group has access to the web services, and it only contains the local admins group and the TFS service account (unless you've modified it). You can read about the group here:

http://msdn.microsoft.com/en-us/library/ms253077(VS.80).aspx

You may need to add other users to this group, or populate some of the other permissions groups in TFS (Project Administrators for various projects, etc).

Also, the URL in your question looks odd - it ought to have a servername section:

http://SERVERNAME.DOMAIN.NET:8080/services/v1.0/serverstatus.asmx

You could start investigating by starting the SQL Server Management Studio and navigate to the SQLExpress instance on your data tier. See if the Tfs databases are running and whether the ASPNET user has access rights for the database.
