I have noticed a couple of other things. Along with not being able to access the Programs folder, I cannot access the Windows, WUTemp and a couple of other folders. On cpu1, in Network Places the "c" drive does not have the shared icon, it just looks like a HD icon, under comments it shows \\Mecorp-1\C, when it should be \\mecorp-1\c. The computer name shows mecorp-1. So how and where is it getting the wrong computer name. Also to the right of comments is Computer and under that it lists the C drive as unknown. Also, when I look in View Workgroup Computers just above where it lists the (2) cpu's it saya unspecified. All of this happened after I did the Windows update.
