Problems with NLB (Network Load Balancing)

We have two Windows 2003 R2 Standard servers with IIS installed. Have configured NLB on single network adapter.
We want to use NLB for Remote Desktop Web Connection. It works fine on one server. But I can not make it work on second one. Servers have different hardware (HP Proliant servers) but are installed identically (MS operating system) and fully patched.
When connecting to NLB address (after disconnecting first server) it works very slowly or not at all. Have tried to configure only second server with NLB but I cannot make it work properly. At the same time the first one works fine. Have tried reinstalling
IIS but it doesn't help

What works slowly or not at all? Remote desktop? IIRC, remote desktop web connection doesn't really involve IIS at, it's a just a web page hosting an ActiveX control that's the RDP client.

Thank you both for fast answers.
Have configured several NLBs before and never run into a problems like that.
This made me thinking to investigate NIC and their settings.
Server is HP Proliant DL380 G5 with NC373i network adapter.
Have played with settings and discovered that after changing Receive Side Scaling do Disable NLB started to work OK.
I don't know yet what that Receive Side Scaling means but I will investigate.

this solved my problem here (using the same configuration). So I can confirm that there is an issue with DL 380, the NC373i NIC and NLB
