Hi all,

Before I start I just wanted to apologise if i have posted this to the wrong forum.

We have a Netware 6.5 server running Zenworks 7 SP1 HP3a. We have just done a major network infrastructure upgrade including a core stack of 2
5500G-EI switches.

Since the install of the switches we have been experiencing really slow multicast times. What i have found interesting though is if I plug the server into a 100mb port on another switch or set the speed to 100mb on the 5500G-EI port there is no problem and the multicast will finish in around 15 minutes.

I have upgraded the NIC driver to the latest version which is 4.61 (BX2.LAN) and this has not helped at all.

Does anyone have any ideas that may help out? I can unicast with no problem they finish in around 15 minutes.
