SBS 2011 slows to a crawl and requires reboot
Posted on 2013-12-02
I have had a number of calls from clients with SBS 2011 experiencing speed problems. Common symptoms are;
-Access to network resources (i.e. shares, printers) becomes very slow
-Currently logged on users can see and use resources but other users are refused logon.
-Can not access server remotely using RDP on any other 3rd party remote software.
-Blank screen on server desktop with mouse pointer
-Can usually perform remote shutdown from LAN.
-Reboot always fixes the problem for several weeks.
The servers are mixed hardware but all HP with HP ROK editions of SBS 2011. All installations are physical with no virtualisation involved. All exceed the minimum required spec, usually 16GB or higher RAM, at least 2 physical volumes in RAID 1, Xeon processor, mix of SATA/SAS drives. All firmware updates installed and every MS service pack/critical update installed.
Performance is always good in every site after reboot and its not like it steadily deteriorates over time but just seems to hit a wall after a random period.
Is there an update/fix that I have missed that may be common across these machines causing these problems?
