windows 7 client and 2003 server: network Slow in very big Network !!

[MohamedAbdullah]

hello engineers,
how r yo all? Guys i need your help.
My problem is windows 7 hangs and freeze when access 2003 server Enterprise edition . This is not a small network, one of the biggest network.
i have doubt on individual users on domain.before 2 months we had department wise users mean, for example [email protected]. But after we created the individual users like [email protected] to all users.
this is i believe the cause of problem. When we acess the server via the software it freezed for 5 seconds and then repeat to normal state. And after some time it hangs for 2 minutes.
we r a big company ,producing daily basis.hmmmm Openly very large media and press company. please any one know the exact problem? Thanks

Hi Mohamed and Welcome to SF,

Pls. check your Server's Event Viewers error logs, especially DNS errors.

What type of Security or AV Software do you have installed in your Server?

Will it be possible for you to post an ipconfig /all output of one Win7 machine and the Server?

Dear Mohammed,
firstly check whether your DNS Server settings are correct. next
Run a packet sniffer tool example wireshark, MS Netmon, and capture some packets and view what kind of traffic is going around in the network. post the results.


Cheers!!

You may just post the Event ID errors DNS related from your Windows 2003 Server.
