I was just wondering, what exactly is that, and how do i do it?

I have 3 networks computers, networked through a linksys router. (thought you might need to know that?)

HMMMM this was probably a dumb question, i think i figured it out.

"HOW TO SET THE PROPER NIC DUPLEX SETTINGS:

Win98/ME: to change to half-duplex:

* Open Control Panel.
* Double-click Network.
* From the scrollable list, select your Ethernet adapter (rather than any dial-up) with a green icon.
* Click the button Properties.
* Click the tab Advanced to bring it to the front:
* In the Property box, the property name to be selected varies according to model of ethernet card. Examples are: Network Link Selection, Media Type, Connection Type, Duplex Mode, or any similarly-named property which can have Values looking like Auto-Negotiation, or 10BT, or 10BaseT.
* In the Value box, select a value which either (a) explicitly says half-duplex or semi-duplex, or (b) at least does not say full-duplex [e.g. 10BaseT on its own is OK]. If there is a choice between 10 and 100 with half-duplex, choose the 10. Do not choose 10Base5, 10Base2, or AUI.
* Click OK to exit the Adapter settings.
* Click OK all the way out - you might need to restart.

Windows 2000 or XP: to change to half-duplex:

* Open Control Panel.
* Double-click Network and Dial-up Connections.
* Identify the icon for your cable modem connection: usually Local Area Connection.
* Right-click that icon and select Properties.
* Under the ethernet adapter icon, click the button Configure.
* Click the tab Advanced to bring it to the front:
* In the Property box, the property name to be selected varies according to model of ethernet card. Examples are: Network Link Selection, Media Type, Connection Type, Duplex Mode, or any similarly-named property which can have Values looking like Auto-Negotiation, or 10BT, or 10BaseT.
* In the Value box, select a value which either (a) explicitly says half-duplex or semi-duplex, or (b) at least does not say full-duplex [e.g. 10BaseT on its own is OK]. If there is a choice between 10 and 100 with half-duplex, choose the 10. Do not choose 10Base5, 10Base2, or AUI.
* Click OK to exit the Adapter settings.
* Click OK to exit the Connection properties."

Was that the thing you needed?

I am pretty sure that protman.dos is actually one of the driver files.  Possibly that release of drivers is bad?  If it is in fact something that should come off of the Windows 98 cd, then it would be in *:\Win98\*.cab.  Just use the search function in Windows and make sure it is set to search cab files.

Found it on an old Windows 98 disc.  Protman.dos is in *:\win98\NET7.CAB\protman.DOS There is a protman.com file in NET8.CAB also, just in case it asks for it.
