A few on the list helped me with a windows file sharing problem from PRO
-> PSN with Gnatbox a few months ago, and basically it boiled down to
using IP Passthrough from PRO to PSN.  The problems were really random
with their timing and after going to Passthrough they've been gone.  It
definately looks like could be your issue.  One way to test is if when
you have the filesharing problems, can you access the PSN box with a
different service (like HTTP or FTP, etc).

Subject: [gb-users] Problems with workstation connections

We've been having a weird problem for a while... Our office is pretty
small, we have 4 PC's, one WAP (supporting a laptop and a printer).

We also have about a dozen users on frame relay attached to our network
as well.

The problem we are experiencing is that when my PC, and my partner
Nelson's PC are both on the PRO, Nelson has a LOT of trouble getting to
the PSN network. Pretty much anytime he tries to access anything on the
PSN, his computer hesitates about 20-30 seconds before loading what he
needs. When I moved my PC over to the PSN, his problems disappeared.
When I move back to the PRO, he has problems again.

We've both rebuilt our PC's (He rebuilt his just to see if he had a
software glitch, I rebuilt mine because my motherboard died) and this
has not changed the problem one bit.

Our PRO switch is a Cisco 3524XL. Our GnatBox is a GB-Flash 3.4.4. We
plan to upgrade the firewall to 3.5 sooner or later, but we just haven't
had the time to do so yet.

This problem is seriously baffling us. I *think* it's the firewall
causing the trouble, but I'm honestly not sure. My PC hiccups once in a
while in a similar fashion, but that's maybe twice a day... It happens
to Nelson constantly, and makes it really hard for him to work. I'm at a
loss however in trying to track down the problem. I'd put a packet
sniffer on the network if I could figure out how in the world to make
the switch co-operate. (The last time I tried to configure one of our
switches to sniff, I somehow wound up rendering the port unusable until
I reset the switch....) I see no error messages in the GnatBox logs. I
can't find any error message up on the servers.

However, I'm fairly confident that something between our two PC's is
pissing off his system. I just got back from lunch a little while ago,
and a couple minutes after I sat down, Nelson came in my office and said
'Well, I figured you must be back...I can't get the network anymore.'

ANY help whatsoever will be greatly appreciated. This problem is so
baffling to me that I can't even come up with a reasonable explanation
for what's going on.
