Citrix Oddities

I have an end user in a remote location that is having a difficult time connecting to Citrix from his home office.

He has a connection to the Internet via DSL and has issues getting on Citrix or when he is connected, things run very slowly.

The citrix server is at the corporate office and is not heavily used... the Internet connection from corporate is a T1.

The Citrix server is a P4 1.5GhZ with 1Gb ram Win 2000 SP4

I am somewhat new to citrix and confused at the slowness.  This user is the only one who sees this regularly.

Does anyone have any thoughts on this one?

I wonder if this could be an issue with the MTU size?  You may want to ck it out.

(I too am not all that familiar with Citrix, but understand its usefullness.)

Should this be configured on the citrix box or the client?

Since many others use ethernet and only a few are connecting via DSL...

MTU resizing is a trial by error process.  But my thinking on this is since you are using ADSL and many providers of this service use PPPoE, the max size of the MTU should be 1492 set on the connecting machine.  Normal broadband (cable for instance) uses 1500.  This should be auto-detected, but it may be fixed too.  If the MTU size is set at 1500, for example, you will have massive fragmentation of packets if you are connection is setup using PPPoE.

Now, recall that I am not all that familiar with Citrix, and this may not be the case at all.  :)

Here are some links if you want to visit them.  You will find quite a bit out there on this subject.

Changing the MTU size in XP (should work in 2000 also)

Sure hope this helps.

I tried modding the MTU value as suggested on one laptop...

I will have to wait until this user is again using DSL from her home to determine success.

thanks a bunch...
