Windows Server 2003 r2 Standard x64 slow windows explorer
Posted on 2010-11-18
Windows explorer performs too slow lately on my WINDOWS SERVER 2003 R2 x64, otherwise when browsing trough locations on that server from XP workstation witch is in LAN everything runs fine.
When click on My Computer & looking at explorer.exe in performance graph of PROCESS EXPLORER
i see that Explorer.exe use 50% of CPU for 1-2 sec. than stays on 25% for 3-4sec.
than finally opens explorer.
Same thing happens what ever i browse while logged on problematic server.
Windows log on - log of is also become extremely slow & is irrelevant do i log locally or remotely using Remote Desktop trough LAN (workgroup) or VPN, logging is always slow.
This server is used for ORACLE DATABASE & this part runs great.
I have tried disabling Kaspersky antivirus+firewall but the problem remains.
HDD RAID5 is defragmented & checked for performance & errors with HDD TUNE.
I'm hoping someone can suggest what kind of diagnostic tool can i use & how to set it up for inspecting the right things.
Server model: IBM x3650
CPU: INTEL XEON QUAD CORE E5320 (XEON E5320 @ 1,86GHz x4)
RAM: 8GB PC2-5300

Network adapter: NIC DUAL GIGABIT
(got two network cards, one for LAN & second for VPN, there's no internet access on comp due the VPN)
