Citrix Caused Immediate Shutdown and Failure

Hello,

The company I work for uses Citrix Presentation Server 4.0 and several uses, including myself, connect remotely using v10.150 of the Citrix client.

Several times, I have had an issue where my remote computer, a Dell XPS M-170, will make a very loud beep and shut off. Not shutdown, just go immediately off. This happens only while connected through Citrix and at no other time. One other employee had the same thing happen to him, again while connected through Citrix.

Generally, when this happens, we just turn our computer back on, reconnect, and can pick up right where we left off.

Unfortunately, when it happened to me the last time, my notebook computer did not turn back on. After trying different batteries, outlets, and several other things, I called tech support and they told me that a complete inability to even have fans power up meant the motherboard was blown.

The question we have here is how is this even possible? The immediate shutdown (and subsequent failure) only happens while connected to Citrix, which is on an infrequent enough basis to rule out coincidence. It doesn't happen every time, nor when performing one specific function. It has happened while sorting records in a database, while trying to defrag a remote server, and while browsing directories on a remote server.

My computer was purchased after the battery recall, and I double checked to be sure it neither battery was affected, so that isn't it. My anti-virus is up to date and my computer is regularly scanned.

Has anyone heard of anything like this before, or have any possible explanation? I'm worried it could happen again after my computer is repaired.

If it matters, the two computers it happened to were my Dell XPS M-170 and another employee's Dell Inspiron (model unknown), both running Windows XP Professional Service Pack 2. Mine is my personal computer, his is a company issued one.

To date, we are the only two employees who have reported a problem. Most other users connect using various Dell Latitude models. I did find out on the Citrix forums that another person had a similar problem, and he, too was running an Inspiron. IIRC, an XPS is an upper line Inspiron, so could this line be causing a conflict of some sort?

I welcome any thoughts or additional questions.

Thank you.
