I have three xp machines all with SP2 current on all updates. Two desktops and one laptop. I could access shared folders last week on all machines.
Today the laptop was plugged back into the network and I can't access shared folders. I can ping all machines all from each other and all machines have internet.
I can't access any shares, not even C$ on any of the desktops from the laptop. The desktops also can't access any shares on the laptop.
The laptop and one desktop are running symantec corp 10 the other desktop is running Norton 2004 antivirus. Like I said earlier they worked last week.
I tried manually configuring the network addresses and DNS and still had same results ping but no access to PCs from the laptop and vice versa.
The two PCs communicate fine though. I'm running a virus scan on the laptop to make sure it didn't get infected over the weekend.
The only change I could get the user of the laptop to fess up to was that she had Wild Blue highspeed installed at her house and the kids played online games over the weekend.
