Please help. Desktop and laptop connected via vireless access point. Printer connected directly to desktop. Previously file and printer sharing worked without incident. Suddenly laptop cannot see desktop (doesn't appear on workgroup, and network locations can't be accessed) Desktop can see the laptop (its listed in the workgroup) but it cannot access laptop's shared files. I decided to ping from each computer to see if they could talk. Laptop can talk to desktop - ping comes back just fine. BUT the desktop has a major error when I ping .... I type the ping and IP address and I get a bunch of garbage on the screen and an error message that says NTVDM CPU has encountered an illegal instruction. CS:0549IP:ffe4OP:feff1d094f
I have no idea what this means - but it seems fairly serious. Like perhaps a registry problem, and maybe it was caused by a virus??? I have a router, with mac address filtering and 128 bit security, plus I use Norton Internet security on the dektop, and norton antivirus and windows firewall on the laptop. I HAVE however downloaded music and other files recently, and I had a big problem with adware on the laptop that forced me to system restore - but it seems OK now, and the desktop has always been clean.
I am going to run antivirus and anti spyware on the desktop now .. if anyone can help me figure this out I would be very appreciative!
