SYMPTOMS
The Exchange Server exhibited apparently unrelated symptoms including the following:

-Every few days, the server would lose connectivity either to the Internet, to the local Lan segment or both. A successful reboot of the server resolved the issue for another 2 to 4 days until the symptoms appeared again.

-For approximately 80% of server reboots, the Exchange services would hang. The Service applet showed them as &quot;Starting&quot;. Rebooting repeatedly until a successful boot was accomplished was the only way to clear this.

-From the console, the mouse moved slowly in some windows, but not in others.

The following events appeared in the application event log:

There may be a problem with this extensible counter or the service it is collecting data from or the system may have been very busy when this call was attempted

Note The atkctrs.dll is the performance monitor counter used to monitor the Appletalk protocol. Refer to the following Microsoft technical article for more information:

When the following services were stopped and disabled, and the server rebooted, all of the above symptoms would disappear:

IMAP4SVC - Microsoft Exchange IMAP4

POP3SVC - Microsoft Exchange POP3



CAUSE
Unknown. Speculation is that the Appletalk protocol was corrupted.



RESOLUTION
Removing File and Print Services for Mac and the Appletalk protocol alleviated all of the above symptoms.

Remove the Appletalk protocol via the Networks icon in the Control Panel.

Refer to the following Microsoft technical article for instructions to remove File and Print Services for Mac:
