Solution: Corrupted updates for Symantec Mail Security (SMSME 6.5)

Upgrade to one of the following versions:

6.0.12 or higher
6.5.5 or higher

These versions increase the time allowed for the copy process to five (5) minutes.

If this issue persists increase the copy timeout using the following steps:

1. Run regedit.
2. Create the following DWORD registry key:

64 bit Operating System: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Symantec\SMSMSE\<version>\Server\DefsUpdateTimeInSecs
32 bit Operating System: HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\SMSMSE\<version>\Server\DefsUpdateTimeInSecs

NOTE:  Replace <version> with the version of SMSMSE installed.  For example on a 32-bit system with 6.5 installed the key is: HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\SMSMSE\6.5\Server\DefsUpdateTimeInSecs.

3. Set the value of the key to be the timeout in seconds.  For example to set a ten (10) minute timeout set the value to 600.
4. Close Regedit.
5. Restart the following SMSMSE service:
