The Path Is Not a Legal Form
by Alena Semeshko
Installing TFS 2008 with Sql Server 2008 can be quite problematic, especially when it comes to the SQL Server Reporting Services.
Here’s a problem a recent discusses.
If you realize your configuration tool has issues with prior installations of software, and the report urls are pointing to a SQL Express directory, it’s best to go over the set up of virtual directories manually. This requires application pool set up.
Chris Eargle in his post suggets that the service user be assigned to run the pool, after which the user should be granted write access to the RSTempFiles folder.
What’s weird, is that at this point an error pops up saying: “the path is not a legal form.”
Alas, here’s a solution:
if you receive this error, you need to add your application pool user to the SQLServerReportServerUser (followed by $servername$instancename) group. It’s that simple, but the error doesn’t indicate what is necessary to fix it.
