Windows 7 Pro workstation in SBS 2003 network VERY SLOW login & network share browsing.
Posted on 2013-01-27
Issues: Windows 7 Pro 64-bit w/ new OS Very Slow login (3-6 minutes) to SBS 2003 server and very, very slow browsing network shares (45-90 seconds to open a subfolder) or accessing network resources (like Exchange server). Old Win XP boxes are almost instant when browsing.
Environment: Affected workstation is about 3 years old, Core 2 Duo w/ 4GB RAM w/ fresh Win 7 Pro OS, very snappy except the slowness mentioned above. SBS 2003 server, SP2 and most updates, Intel box, dual quad core Xeon processors, 4GB, RAM, plenty of free space on 2 RAID arrays, 500GB each, windows level Mirror (I inherited this…no idea why previous tech did this w/ very nice RAID controller on Intel MoBo), server performs well, especially given its age. About 4 years ago I “reclaimed” a client that had a 1 year old server, at that time. The server had multiple very odd issues we discovered when we 1) implemented normal use of the Exchange server, 2) implemented RWW for a user. I won’t bore you with the details but we got things working properly but I mention it because it may be relevant to the current issues.
The workstation worked normally on our workbench during OS load and installation of multiple software programs in preparation for introduction into SBS environment. Joining domain went normally up to the point when the normal routine of rebooting and logging in the domain for the first time…very slow!! After this slowness, I set IP & DNS static to assure SBS server was the only DNS server…no improvement. I check the server to verify the machine was in the correct organization computer group. I updated the BIOS and NIC driver to the latest versions, no improvement. I also tried this I found in a technet post “If it does not work, please also configure Send LM & NTLM - use NTLMv2 session security if negotiated (Level 1) for the Group Policy “Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options
”: Clients use LM and NTLM authentication and use NTLMv2 session security if the server supports it; domain controllers accept LM, NTLM, and NTLMv2 authentication.” Oddly, it seemed to help for about 20 seconds then the speed came to a crawl again.
I’m at my wits end…any help is MUCH APPRECIATED!!!
