Win2003 Server random restarts Event ID:1003

Not open for further replies.
My server Win2003 OS randomly restarts (1-2 times a day)
I get following error message in Event Viewer:

Source: System Error
Category: (102)
Event ID: 1003

Error code 00000050, parameter1 a2f517fc, parameter2 00000001, parameter3 f61b4fe9, parameter4 00000000.

Can't find any issues with configuration, and I suspect that the reason is a hardware (possibly RAM)

Since I do not know how to read the minidumps - maybe some kind soul will help me figure out the culprit.

One of the minidumps has code memory which is the symptom of faulty memory. It coulbd be caused by faulty ram or PSU.

The culprit is faulty memory. You can run memtest to stress the ram. If memtest reports the ram is faulty, ram is bad. However Memtest is not a perfect tool to test the memory as some faulty ram can pass memtest.

1. Check the temperature of the CPU and make sure that it is not overheat (ie temperature < 60C)
Make sure that the CPU fan works properly
2. Reseat the memory stick to another memory slot. Reseat video card as well.
3. Downclock the ram. Check to default setting if you video card is overclocked.
4. Clean the dust inside the computer case
5. Make sure that the ram is compatible to the motherboard
6. Check the bios setting about memory timing and make sure that it is on
For example : DIMM1 and DIMM2 do not have the same timing.
DIMM1: Corsair CMX512-3200C2 512 MB PC3200 DDR SDRAM (2.5-3-3-8 @ 200 MHz) (2.0-3-3-7 @ 166 MHz)
DIMM2: Corsair CMX512-3200C2 512 MB PC3200 DDR SDRAM (3.0-3-3-8 @ 200 MHz)
DIMM3: Corsair CMX512-3200C2 512 MB PC3200 DDR SDRAM (3.0-3-3-8 @ 200 MHz)
7. Make sure that your PSU have adequate power to drive all the hardware including USB devices
8. Run chkdsk /r at command prompt

If it still crashes, diagnostic which memory stick is faulty
1. Take out one memory stick. If windows does not crash, the removed memory stick is faulty.
2. If you have only one memory stick, replace the ram

Thanks for quick reply,
I will remove one of the DIMM's and see what will happen.

I have yet another server that reboots now every 5-6 hours and I get EventID: 1003 as well.

Checked for viruses etc. with no results. This server was in service for quite some time, and had no problems until recently. Is it memmory again?

Attached are minidumps from this one - by the way - how do you view minidumps?

The priblem may be related to software error at b57xp32.sys (ethernet card driver) or faulty hardware. Upgrade b57xp32.sys. Repost if your windows still crashes.
