I have a Remote Loader Service running on a 2008R2 Member Server.

It was running fine for over a year. I installed the following MS
Patches on Tuesday the 10th and Symantec Endpoint Protection was
upgraded on Wednesday the 11th.

On Thursday, the 12th, I noticed that changes were not Syncing as of
1pm. The RL Service was running, but the following message was
displayed in the log file:

DirXML: [01/15/12 00:38:38.37]: ADDriver: driver destroy
DirXML: [01/15/12 00:38:38.38]: ADDriver: Driver::~Driver()
DirXML: [01/15/12 00:38:38.40]: Loader: Waiting for DirXML to connect on
'TCP server socket, port 8090, address 172.x.x.x'...

Restarting the 2008R2 Member Server and then restarting the AD Driver
seems to temporarily fix the issue-it happened again this weekend...and
I'm hoping you've seen this recently and could tell me which MS Patch
may have caused the issue:
