We get this problem too.  Our fix has been to toggle the switch from Full
duplex to Auto, and then back to full.  No reboot needed. Takes about a
minute. Changing it on the servers didn't seem to help us.    Instead of
Half duplex, our switches said we were running at Symmetrical duplex
(Enterasys switches).  The problem only occurs when we install the NIC
drivers from the Smartstart 5.4 CD.

FYI:  I thought I would post this since I know there are several people
Compaq DL580's for MetaFrame servers.

We had an issue where our Compaq DL580's integrated NC3134 NIC were
running in a degrading Half Duplex mode even though they were set at 100
Duplex.  I have been working with Compaq on the issue and was informed
there is
a known issue where updated NIC driver 7.10.710.15 (that is suppose to
issue) is not correctly updating a required registry setting.  To fix the
issue, the server(s) duplex mode need to be changed to another setting (ex:

Half Duplex), rebooted and set back to 100 Full Duplex and rebooted a 2nd
 I applied the fix procedure to my servers and it seems to have corrected
