If nothing shows in the logs I would take a look at enabling some
Performance Logging for CPU and memory which could show if use of either had
increased dramatically before the failure and could post alerts in the
system or application log if certain thresholds you describe are crossed.
Otherwise it could be hardware related for power supply, CPU overheating, or
flaky memory as top suspects for hardware issues. The link below explains
Performance Monitoring basics. In cases where I have had similar problems a
fresh install of the operating system often fixed such problems for me if it
was software related problem. --- Steve

yes...temporarily it fixes the issue. It was 12 days between failures the
last time around now it seems like it is failing again a mere 7 hours
later after my last reboot.

Does a reboot fix the problem?? Maybe enabling performance monitor
logging for memory and CPU can give you an idea of what is going on. It
could also be a hardware problem such as a flaky power supply or
overheating CPU but those problems are usually not as regular. --- Steve

The only problem is that it is running along fine and then goes out the
window in a matter of a minute or two and this is making it difficult to
see what state the system is in at the moment it starts happening.

Does a reboot solve the problem? If so it sounds like you may have a
memory leak on some process. I have not tried it myself but there are
some Resource Kit tools called memmonitor and memtriage that may help
troubleshoot such as shown in the link below. As soon as you experience
reduction in performance be sure to check Task Manager for memory/CPU
usage and it would be a good idea to use something like Process
Explorer from SysInternals to save a baseline of what memory and CPU
usage is for your processes when everything is running well. ---

I have a Dell PowerEdge 2550 server running Windows 2003 SP1 and have
strange behavior occurring every 7-14 days. The server will always
respond to a ping however when the problems start, I notice services
start becoming choppy in response and eventually do not respond at
all....when it gets into this state, I cannot access the system with
RDP and the actual system console loses the Ctrl-Alt-Del screen which
was displayed prior to the trouble starting.

The server runs the following apps/services

IIS 6.0
Windows SharePoint Services
MSDE for SharePoint
XWall 3.34

The server is protected by firewall appliances and the event logs show
no signs of any trouble on the system at anytime. A straight 2 hour
Dell hardware diag run reflected no problems on the system whatsoever.

Any idea what direction I can take to resolve the issue? I'm
convinced it is software and maybe even specifically with the lsass
engine but can't confirm without any event entries to go on. This
doesn't happen frequently though it does consistently happen. The
server has 3GB of RAM and everytime I look in on it, it has more than
half of the physical RAM available with normal paging.

I'm stumped....I'll call PSS if I have to but the problem is I can't
force the problem to occur making it more difficult to troubleshoot.
