SBS2003 System on HP Prolient unresponsive once per hour

Posted on 2011-04-29

I am running SBS2003, not R2, but fully updated, on an HP Prolient ML150 G5.  I beleive it has 8 gigs for RAM installed, although it only shows up as 4 gigs due to 32bit limitations.

The problem I am having is that once per hour the whole network seems to stall out (workstations cannot access shared drives, printers, and programs running off the server become unresponsive - and if working on the server directly the server appears to freeze up for a time).  This always happens around the turn of the hour (usually 2-3 minutes before the hour, and lasts usually for 1-3 minutes).  I have looked through my event logs, but nothing is jumping out at me - although there are quite a few application messages basically saying that the server was unresponsive at that time.  These messages are a symptom of the problem though, not the problem itself as far as I can tell.

A little more info about this server.....
 - it runs exchange (fully updated)
 - it shares files with about 6 other workstations
 - it has SAGE ACCPAC ERP installed on it - with normally only one user logged on at a time - it uses a PERVASIVE Database.
 - Kaspersky Antivirus 6
 - Choicemail Enteprise Installed (Spam blocking software)
 -  MSSQL Server is installed - allthough I am not sure what it is all used for (it was used for some previous software on the server - and I think is currently used by Kaspersky.

 My first thought was that there was a scheduled task running once per hour.   The performance monitoring task was set to being run once a day, and to be repeated once per hour (15 minutes before the hour).  I dissabled this task, but it did not make a difference.  For troubleshooting, I also dissabled VolumeShadowCopy task, even though it was not set to run once per hour. This also did not make a difference.

If you think it could be at all related (I will post this as another question if I cant find the solution myself), when I run the SBS2003 Best Practices Analizer, it comes up with one critical allert "The DNS Client is Not Configured - The DNS client is not configured to point only to the internal IP address of the server."  When I check all the workstations on the network, they all look to the server IP for DNS.  The Server NIC is configured to point to the the router.  This is a single NIC Server.  

Thanks in advance for any input.

    You say you have no scheduled tasks but Kapersky updater runs periodically even though it's not listed under task scheduler. I'd disable updates temporarily to eliminate that possibility.

    Kaspersky is set to run once per hour - thanks for the pointer.  Also, I have noticed that up2date.exe - kaspersky's update program - runs during those 'unresponsive' times.  It takes about 25-30 mb of RAM and up to about 15% of CPU.  I have changed it to run once per day, in the middle of the night, and will monitor the server for a couple days and post back.

    There is an up2date fix if that's it -

    Regarding the DNS settings that you get the warning from with best practice analyser you should just list the server's own IP address under DNS on TCP/IP settings page, and under DNS server which is on the same machine set it to use your ISP's DNS server as forwarder.
