Invalid RID: No repository manager found for prefix: /documents

Hi,

I am using EP6 SPS14 on WAS 6.40.

I am getting the following error on my Home Page in the Portal :

"Invalid RID: No repository manager found for prefix: /documents".

I am not being able to see any documents or check whether the Repository manager is running or not.

Nothing is working.

It was working fine till yesterday.

I have not done any changes except that i detached the "tbp" service form "/documents" and attached it back again and restarted the server.

Pls help me on this ASAP.

Its really urgent

Thanks a lot

Saurabh
