Hi Again,
Some simple questions...
1 do both computers see the internet
2 is this a new setup with the two computers or had this been working once before
3 confirm the following on both computers. Right Click on My Computer. Left Click Properties. Left click Computer Name. Does Computer Description, Full Computer Name and Workgroup have information in their entry fields? Keep names simple, short and no spaces or characters other than letters and numbers. Computer Description is for humans to understand (I named mine Doc), every computer will have a different description. Full Computer Name is what windows uses, every computer will have a different name - again short, simpe - letters and numbers (Mine is S1). Workgroup - always short letters and numbers in capital letters!!! all computers will have the same description.
make changes as necessary. windows does not reconfigure itself well on restarts. turn off computers for 5 minutes and then turn on. does it work?
if not let me know... there are only about 999 other things we can do.
Good Luck - FireDoc
