Running Windows Server 2003 R2 SP2 w/16GBRAM. I noticed svchost.exe sometimes using 1.5GB of physical memory. Checking with Process Explorer showed this particular PID as DNS Client and DHCP Client services. I disabled DHCP Client since this server has a static IP, and memory usage dropped to 400MB yesterday. Now this morning, it was at 400MB or so. LAter this morning, svchost.exe is back up to 1.5GB even with DHCP client disabled. I noticed after a certain user logged in to TS on this server, if that makes any difference. System is clean of all malware/exploits, etc. Any ideas for the huge memory usage for svchost.exe?
