I have the same problem and have not yet been able to find any answer on the web, SSRS 2008 R2. Remotely over VPN is so bad editing just a date in the subscription, well it's still waiting for a reply from the server.... it been over 10 mins... Time to kill it.. From the office it takes about 5 mins to perform any task to the subscription...

Does anyone have a idea? I'll be checking with the DBA and ask him to gather information about auto grow size and Temp DB sizing...

Love to hear some answers and/or ideas from this group,.... please and thank you....
