I'm evaluating version 3.5.3 of Sourceoffsite. I have crossed one error after another thanks to this Group.
I currently face this error :
Server Error 400
I have tried all the suggested solution :
a. Giving default Launch permission for the user from dcomcnfg.exe
b. Enabled user permission on the network drive
c. Ran an analyse on the database.
However no luck..

I see that the Logging is enabled to Log.txt but there is no log.txt file in the SourceOffsite folder. (i thought i shall send that file for your investigation).
I get a message of "Server Closed" in SourceOffsite explorer, "operation failed - (null)" in bottom window of SourceOffsite explorer.
The following messages appear in the Event Viewer :
1. Connection Established
2. "admin" connected to database: \\150.122.50.20\ECommerce\srcsafe.ini
3. Server Error 400
4. User "admin" disconnected
Please provide some helpful hints to proceed further.
Thanks
Vaidy
