Have 3 comuters running XP SP2. 2 have professional, one is home adition. One of the PCs can not access shares on one of the other. I can map a drive, and see directories, but if there are files, the connection will drop after a while, and I can not access anything at all. Have checeked security (share + ntfs), firewall and IP-settings. Looks OK. The PC can access shares on other PCs and other PCs can access the share which is not accessible from the troblemaker. I use the the same account from all computers. Computers are in a work group. No erreors in event logs. Anyone that can advice me?
