What did he work on?
Maybe switches\routing? Perhaps he has created problems by rearranging the
uplinks or maybe a conflict with 10/100 vs Gb ports\switches\nics.
Maybe ACLs created on routers or some other fudging. Had that happen
recently at a site where jr. tech created loop by incorrectly placed uplink
and same thing where the Citrix servers at that site where up and down till
someone discovered the mistake.

Subject: [THIN] Known ICA vulnerabilities?
We had a Network Engineer leave (not on good terms) and since then I've been
experiencing problems with our Citrix servers locking up. Maybe I'm just
paranoid but the problem started happening right after he left and generally
occurs between 10am and noon (never had problems before this). It doesn't
happen everyday but has occurred on both of our servers (win2K SP4/PS4). The
server seems to just go slow with no disk or CPU utilization.
Are there any known ICA vulnerabilities? Both of these servers have port
1494 open facing the Internet. Any suggestions would be most helpful as I
can't get on the server to diagnose when the problem occurs and all logs
show things are normal.
