I've napped a network drive before and can not recommend doing it for the home PC network. Sure it works and I've even had people from Kazaa downloading from it but you aren't going to be able to do much else with the PC and if you boot up and that resource isn't available then it will act like it's hanged. For the home user Explore will let you get anything you'd need from any computer so why would you want the extra overhead on your system. I think it is just there for corporate use where they use dedicated servers that are up all the time.
So back to the orginal problem here...
I have to assume that you had a working system and this is not a new install and that only one PC went down and you can get on the Internet with the other one.
1)Download this file from here...
http://members.shaw.ca/techcd/WinsockXPFix.exe
(the source is from our good friends at...
http://cexx.org/lspfix.htm...the page it's on)
2)On the computer that has no internet access; Force a valid network address like the usual...Specify an IP address...192.168.0.X and a mask if you need it 255.255.255.0 and get the intranet working and copy that file (WinsockXPFix.exe....1.3Mb) over and execute it on the PC. It should fix your problem it even puts it back to...Obtain an IP address automatically.
From the source it says:
Winsock repair utilities written by others
I want to add that it should be in everyones first aid kit...just imagine if you only had one PC in the house!
