Hi Chris,
I like changing the MTU'S on my machines just for GP. You can find the
default values
On this link from MS
http://support.microsoft.com/default.aspx?scid=http://support.microsoft.
com:80/support/kb/articles/Q140/3/75.asp&NoWebContent=1
You can also use the ping command:
ping -f -l 1420 192.1.1.1 (enter your IP) and try different settings
this example uses MTU size
Of 1420 but when you switch to 1550 for example, you will see that the
item becomes fragmented.
You can also use the attached vbs script to make changes to MTU's your
machines. Just set the
Value to what you like from the 1440 that is listed.

Subject: [isalist] Blue Screen while using Citrix Client
http://www.ISAserver.org
Hello.
I am wondering if someone else had this problem.
I am finding that when we use the Citrix Client internally to connect to
a host outside of your network, the ISA Server will crash and receive a
blue screen. The error that is reported is as follows.
STOP: 0x000000D1 (0x0000000D, 0x00000002, 0x00000000,0x0000000D)
DRIVER_IRQL_NOT_LESS_OR_EQUAL.
I've tried systematically applying all updates and service packs to the
O/S, Windows 2000 Server to see if this would correct the problem. It
did not. I tried applying Service Pack 1 for ISA Server (it referenced
Q293161 in it's hotfixes), but the same occurs. I have also tried using
the latest Citrix Client but to no avail.
Q293161 references this as well.
"The error message might also occur if IP routing (ICMP pass-through) is
enabled and a ping (ICMP) packet that is larger that the MTU setting is
sent to a remote host."
Can I manually change this MTU Setting?
Any help would be greatly appreciated.
TIA.
Chris
