Hi Friends,

We have a samba domain controller running on CentOS. when we are trying to add winxp client machines to the domain it is completed successfully,but when i am trying to connect win7 clients to the domain it is giving an error ''the specified domain either does not exist or could not be contacted'' that it cannot find the domain. Please anyone help in this issue as its very important for our network.

Win7 is a problem in many ways.
There is not enough detail in your message to provide a "smoking gun" that might point to the real issue.
You might try these things:
1. Win7 - Check and disable "home networking", if you run a mixed network using traditional methods it only slows your throughput to about 50%
2. Win 7 - Check your network properties on your interface. You want to allow 40 bit encryption (default for XP and below, 7 defaults to 128 which can make it incompatible.)
3. Linux side - check the configuration of your FTP server to see what IP it is listening on. Should be all.
Check this using "netstat -a|grep -i ftp". If the ftp listener is on 127.0.0.1 ONLY, then it is set to ONLY listen to localhost connections, not external.
4. Linux side - check your settings for firewall and selinux. If all else fails, disable firewall for a bit and test that way. If it works, you may need to change your firewall settings to allow teh ports for FTP inbound.


After trying/checking those, retry and let us know if it works or not. If it still fails, also report your findings and what symptoms you see.
