[THIN] Re: Network Optmization : Output queue length very high

We were running MF 1.8 SP4 for W2K, with W2K SP3, GB Nic's, and Office XP.  
Users sessions were freezing up often.  I disabled Ctfmon per an MS article and 
the problem went away.  We are still using GB Nic cards.  We use HP/Compaq.  

Just an FYI on my experiences.

Thanks

There were many issues with Gigabit cards and the results were exactly what you 
have described. In some customers we simply had to disable them and use 100MB 
ones. That fixed all the issues. You may give that a try for testing purposes.

When you say the other servers have the same problem, presumably you mean the 
network queue length? I cant imagine it will be, but try add the Bytes Total/s 
and see if the LAN's throughput is saturated. Are their functions "slow" at 
all? ie, bringing up directory listsings or working with the sql server?

Whats the backbone of your network, switch/hub/make wise?

Oh, and its Xeon, not Xenon ;)

We are running office XP Pro Enterprise SP3.
Yes we are running Dells with brodcoms on the 6 citrix servers but the other 
servers are Dell with installed 3Comm Gigabit NICS that we installed and are 
getting the same problems.  BTW: these problems do occurn on the LAN and the 
sessions that are frozen do show active. 

Thank you for the suggestions tho,

Bruce Jarrett-Norton

If its easy to do, try a different NIC in one of the MF servers and see if that 
helps, people have had various problems with broadcom nics (I assume you're 
using Dells??). But have a look at the following first-

As for the stuttering, what happens if you're on the LAN with the servers, do 
you get this? If not, I'd suggest looking hard at bandwidth usage on your 
external connections, they may be very well saturated. (Also check ping times 
over them!)

The frozen sessions I'd hazard a guess at being sort of the same thing, but 
more extreme. Does the session show as Active or Disconnected when they report 
this? You might find setting up the whole Keep Alive keys thing will help this 
a little - they will be disconnected rather than frozen!

There may or may not be something deeper going on, in which case someone else 
may well provide more of an insight, but the above is what I'd look at!
