Running NW 6.5 SP 5 and Zen for Desktop 7 SP 1 HP 6.

Trying to get PXE working for the first time. Client sees the PXE server
and starts to boot in. However, it stops after it finds the boot server
and displays the following:

PXE-E35: TFTP read timeout
PXE-E39: TFTP cannot read from connection

And it closes out after that. I looked through the forums and I have tried
installing the winsock patch that everybody talked about, however I still
have the same error.

I tried using a TFTP client and I was able to connect to the TFTP server
and download a file without a problem.

Anybody have any idea why it's doing this? Is something not configured
right? I followed the documentation and didn't run into any error until

Thanks in advance.
