Sigh, I always forget where the TCP/IP stuff is. Can you give me a clue? Thank you very much.
Oh, and about my "problem" searching in XP, just typing it here I had a lightbulb moment and went to the Microsoft website (hadn't thought of searching there) and found out what I have to do. It seems the search function on XP ignores all extensions except the common ones and you have to do some stuff to make it search everything, including, if all else fails, changing the registry. I'll try the simple fix and if that doesn't work, well, I've never had to do anything to the registry and since it isn't my computer I need to search on, I think I'll pass on that one.
Thanks again.
Not easy. This is win2000:
Select: Start | Settings | Control Panel
Double Click "Network and Dial-up Connections"
Double Click "Local Area Connection"
Button: Properties
Double Click "Internet Protocol (TCP/IP)
Subnet mask is right there. If you're obtaining your IP address automatically, this might not be the problem. If the numbers AREN'T grayed out, match the numbers.
