Error NetLogon then Srv in system event log

[bobmihada]

Environment: 1 PDC (Active Directory) / 1 SQL2k BOX / 1 WEB SERVER
All have the lastest hotfixes and SP4.

Web server periodically logs:

Event Type: Error
Event Source: NETLOGON
Event Category: None
Event ID: 5719
Date: 01/03/2004
Time: 1:43:33 PM
User: N/A
Computer: %
Description:
No Windows NT or Windows 2000 Domain Controller is available for domain %d. The following error occurred:
Not enough storage is available to process this command.

Followed by:

Event Type: Error
Event Source: Srv
Event Category: None
Event ID: 2019
Date: 01/03/2004
Time: 1:44:44 PM
User: N/A
Computer: %
Description:
The server was unable to allocate from the system nonpaged pool because the pool was empty.

When we try to restart IIS Admin service we get (for all 3 services):

Event Type: Error
Event Source: Service Control Manager
Event Category: None
Event ID: 7023
Date: 01/03/2004
Time: 1:51:07 PM
User: N/A
Computer: %
Description:
The World Wide Web Publishing Service service terminated with the following error:
Not enough resources are available to complete this operation.


This occurs when a user tries to login to our website. When ever this occurs the web server typically has to be rebooted. Running IIS 5 with Digest Authentication to access secure section. Also have COM+ components to serve up the content for the secure pages. All users have account in Active Directory. No error are logged on the PDC or SQL box.

It seems like the web server fails to locate the PDC to authenticate the login requests. Additionally, terminal service hangs or drops the connection. When trying to reconnect, it just hangs.

Any ideals?

Event ID 5719 - The system cannot log you on now because the domain "name" is not available."
Symptoms: when attempting to logon a domain, you keep getting an error that &quot;The system cannot log you on now because the domain &quot;name&quot; is not available.&quot; Also, Event viewer shows Event ID: 5719. No Windows NT or Windows 2000 Domain Controller is available for domain <domain name>. The following error occurred: There are currently no logon servers available to service the logon request.

Resolutions: One possible cause of this error is that you have run out of buffer space in the NetBT datagram buffer. To resolve this problem, increase the MaxDgramBuffering value from 128 KB to 256 KB. Run Regedt32.exe, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters. On the Edit menu, click Add Value, and then add the following information:

Value Name: MaxDgramBuffering
Data Type: REG_DWORD
Value: 0x40000
