Morning All Any help on this one would be appreciated! 2 days ago at between 7-9am in the morning a server of ours becomes un responsive. You cannot RDP to it, although you are still able to ping. Outlook clients are unable to connect at this point. A reboot brings the server back online and we see lots of SRV errors during this period. I am not really sure where to begin trouble shooting this. The server has been fine and healthy up until two days ago. Our monitoring software is not reporting any hardware issues at all. The events we are seeing are: Event Type: Error Event Source: Srv Event Category: None Event ID: 2000 Date: 01/06/2012 Time: 07:31:50 User: N/A Computer: SERVER-SBS-2K3 Description: The server's call to a system service failed unexpectedly.
