Download and Upload through 100Mbit Full Duplex.

[salimwng]

I have two PC's ( Penium 4 with 512 Mb DDR Ram ) both running Windows XP Pro and having 3COM NIC Card ( 3C905C-TXM). The speed of both computers are 100Mbit and both can see each PC in --> My Network Places --> Microsoft Windows Network Places --> AWDOM ( which is the Workgroup name of both PC). I would like to add that both machine have same subnet mask.

The problem is that when i want to download or upload data from each PC, it takes tremendously lots of time. But when i connect my third PC ( which is a Win2000Pro box ) having same type of NIC Card, same WORKGROUP and same subnet mask, the download or upload time is within seconds for same size of file.

What does it take so much time on the XP Machines ?

I have checked at the Folder Options ( under tools ) and i have noticed that their is no check in the "Use Simple File sharing"

Thanks for any suggestions.

Thanks for replying.

The configuration of both cards are set to 100Mb Full Duplex speed.

Hello salimwng,

You did not answer what you observe following the article q315237 as per bcastner's posting.

The article basically tells you two things.
[1] Specifically for Intel EtherExpress 100B network adapters---which yours might not be, add a value to the registry to enable adaptive algorithm provided by this adapter. This would reduce the chance of collision "adaptively" ie intelligently. The starting value can be "1" just to enable it first. Other value can be more specific to technical detail. The .reg layout would be this.

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\e100bx\Parameters}
"Adaptive_ifs"="1"

[2] Else, generally, a workaround would be to add a value named TcpWindowSize to 2920 (decimal) regulating the traffic. The .reg layout would be like this.

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"TcpWindowSize"=dword:00000B68

Do a manual inspection of the respective registry entries and decide the course of action.

1. The 3C90X are essentially B-chipset based, or use a slightly new version of the B-Chipset.

The intergap registry should be made, as described in my earlier post.

2. Most assuredly make the RWIN registry change.

How would i add the REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"TcpWindowSize"=dword:00000B68

To my reistry im interested in speeding up my network speed sharing (98se > Xp > 2000)

Is their a cmd of this someone could help me make?

Hello noellees,

Just make out a plain text file with the content exactly as the code window above shown (including the two blank lines). Name the file with .reg extension. Double-click on it normally would run the import.
