Event 2019 and Server stops accepting new network connections

[Jan]

I've got a windows 2000 server on an NT4 domain.
I've got it patched completely up to SP4.

Lately, after about a day of running, clients on the
network are unable to reconnect to the server via existing
mapped drives, and are also unable to print, since this
server is the print server for a networked HP printer.
After users are suddenly unable to reconnect, I get event
2019 in the event log which says "The server was unable to
allocate from the system nonpaged pool because the pool
was empty". I've found KB article 289209, but it simply
states to install the latest service pack, which I re-
installed with no help.

The problem seems to be resolved after I restart the
system, but after restarting, it takes nearly 10 minutes
for anything to show up in the Network and Dialup
connections dialog box. I seem to be having lots of DCOM
errors after startup as well, so I'm not really sure where
to begin.
Any help or ideas would be greatly appreciated.

I am having the exact same problems with a win2k server in an nt4
domain, it has now started on another server which has been fine for
months and we havent installed anything on it recently. The only thing
i have been able to point out is sql if you have that running?? as ours
seems to be eating ram!!

If you do ever fiond out what causes this please let me know, or email

this may help, quoted from http://www.howtonetworking.com/wineventid.htm
Event ID 2019, 2020, 2021 2022
"Windows cannot logon you because the profile cannot be loaded"
"Insufficient system resources exist to complete the requested service"
"Not enough storage available to process this command"

Symptoms: Some hardware like 3COM Dynamic Access Protocol and USRobotics PCI 56K faxmodem, and software such as Symantec's Norton AntiVirus, Open File Manager and overloading services can cause to leak non-paged pool memory. You may get the following symptoms.
1.You may receive Event ID 2019, "The server was unable to allocate from the system non-paged pool because the pool was empty".
2. Your server may lose network connectivity with its clients and report the following errors in the event log: Event ID: 2020, "The server was unable to allocate from the system paged pool because the pool was empty".
3. Event ID: 2021: Server was unable to create a work item n times in the last seconds seconds.
4. Event ID 2022: "The server was unable to find a free connection 4 times in the last 60 seconds".
5. Your server may stop accepting new user connections and you may receive this message "Windows cannot logon you because the profile cannot be loaded. Contact your network administrator. DETAIL - Insufficient system resources exist to complete the requested service."
6. You may receive the following error: "Not enough storage available to process this command".
7. If you keep getting above errors without fixing, the server may need to reboot.

Resolutions: 1. Apply the Latest Service Pack.
2. Apply the Latest Device Driver Updates.
3. Examine the Hard Disks for Errors and Defrayment the Hard Disk Drives.
4. Upgrade or apply SP to the suspect software.
5. Try to maximize the resources that can be made available to the Server service. This may eliminate the error messages or only lessen the frequency of the errors.

I had the same problem. It took two weeks to track it down. You have
to go to Task Manager and go to the Processes Tab and add the NON PAGED
POOL Column and monitor that. You'll see what service or application is
using it all up. It's not the RAM you need to monitor. It's the NON
PAGED POOL. See my post on Google Groups:
