Windows XP Disconnected Network Drive problem - Drives lose mapping

I am facing issue with Windows XP. The network drive keeps on disconnecting at its own. First the network drive was stable and was working really well. But now the issue is more annoying. I had configured a logon script on boot. This logon script automatically connects the network drives. The same location is also used for data backup but now it is not working. I check inside the logs also but there are no error related to that. I have to manually remap the drives and sometime it fails to connect. Does anyone has any idea on the behavior.

Looks like some kind of problem with the network drive. It is essential that you must simply configure the lan once again. Update drivers, manage permissions, etc and check other connectivity options. This will help you more in dealing with the problem that you are facing. Once everything is fine trigger the script once again and check back. I am sure it will work fine.
