Hello,
make the client computer pointing to your DC as primary DNS server.
Also, check connectivity using ping IP -t command. Check if there failures. If yes then possible that you have problems with your network equipements.
Disable all security softwares that you have and check again.
For monitoring, you can use a sniffer like Wireshark.

Hello,
slow performance starts on the used hardware and ends on configuration settings on the NIC. If hardware like switches, routers and computers is too old or do not use the up to date drivers make sure to update them.
As you run a domain very often DNS is misconfigured. Please post an unedited ipconfig /all from the DC/DNS server and a client that is slow.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Please check connectivity.

Hello,
if the second DC/DNS is configured the same as the first one it seems to be ok from the ipconfiguration.
Are the servers using SP2 and all latest updates? What about the machines with Windows XP, SP3 and latest updates?
How exactly do you realize the slow network, please add some examples?
BTW: ADC = Active Directory Connector, complete different then where you it using for.

Well Regarding Updates i am not sure Coz Some Systems are crack and some and using Genuine Windows.
& ADC for Additional Domain Controller...

Hi Jazaib,
Thanks for posting here.
I think this issue is more better to start troubleshooting form your network derives cause all your internal clients in this network seems are impacted by this issue.
Since you are using Cisco devices, you may try to collect the traffic status by using NetFlow based utility or maybe acquire a better method to verify your network
usage status by consulting with Cisco support service .
http://en.wikipedia.org/wiki/Netflow
On Windows side , deploying SMNP on client is a way for you to collect the network traffic status on client.
Thanks.
