There is a way, but it's difficult.
NOTE: This ONLY works with Windows 98.
Bring up Registry Editor, and find \HKLM\System\CurrentControlSet\Services\Class\NetTrans.
Under there, you'll find a number of keys, starting with "0000". Go through them, and find the key that has the IP address he uses at work.
Once you find it, click "Registry" on the menu bar, and then "Export Registry file..."
When the option comes up, name it "work" and put it on the desktop. For "Export range" you want to select "Selected branch"
That will save all the current settings. close Regedit.
Right-click the file, and select edit.
Carefully, modify the "IPAddress", "IPMask" and "DefaultGateway" entries for your home network.
Save the file with the name "Home" or something that denotes it's your home network, and not work.
In both files, if you want, you can delete the rest of the lines. You MUST save the top line:
REGEDIT4
and the key line: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans\000x]
and the lines you modified.
Now, for your dad to connect at home, he has to right-click the "Home" file, and select "Merge", then reboot. For work, he has to right-click the "Work" file, select "Merge" and reboot.
Cheers!

PS: I'm also a Cisco guy. Tell your brother I said Hi. This has very little to do with Cisco's, though, and a heck of a lot to do with 98. If he needs any REAL tips on Cisco gear, to post it, and I'll look at it.
