The following errors are found in the Public Folder Source Agent (PFSA) log:
"5/28/2008 3:15:21 PM SyncMachine::SetDB Error 3800 'root_folder' is not an index in this table."
"5/28/2008 3:15:21 PM SyncMachine::Init Warning 2262 Cannot create the database 'Q:\emwstp.dat' for tracking messages and folders."
Corruption of the database by some process in the environment while the agent's database is open for read/write operations. This process could be any backup or anti-virus utilities.
You can solve this issue with the PFSA by renaming the tracking database "emwstp.dat" on the root of drive where agents are installed.
Stop the PFSA
Rename the database on the root of the drive to something like emwstp.old (note the location of the database in the error message).
Restart the PFSA.
