Specs: Windows 7
Before our PC OS is Win XP and the file server is W2K, but after our PC update to Win 7 (professional), the file sharing become unstable, sometime it can work normally, but sometime I can't find the file on the network but I can ping the file successfully. and sometime when I want to open the open from the server, it will hold my computer up until i need to restart to server. Every time when I have the problem, I need to restart the server then it will run normally for a while, then the problem again. See anyone can help to fix the issue.

On your Win7: Run secpol.msc > find the entry for
"Network security: LAN Manager authentication level -> change
it to :"Send LM &NTLM - use NTLMv2 session security if
negotiated"


Restart machine and try again.

Does W2K server also need to do the similair action?
And will other PC affect the server if the PC not configure the Network security setting?
Since the problem is still but the frequent becomes less.
I just configure my PC only.

Hi Ern Lai.

Yep. By default both WinXP and Win2k uses NTLMv2. If not, you
could force all client to use NTLMv2 via Group Policy. Once all
client go for NTLMv2, then you can change Win2k server to use
the same.
