Hi, I get event ID 11050 in the workstations' event log
on my network. the description is:
"The DNS Client service could not contact any DNS servers
for a repeated number of attempts. For the next 30 seconds
the DNS Client service will not use the network to avoid
further network performance problems. It will resume its
normal behavior after that. If this problem persists,
verify your TCP/IP configuration, specifically check that
you have a preferred (and possibly an alternate) DNS
server configured. If the problem continues, verify
network conditions to these DNS servers or contact your
network administrator. "
I have IP Security running--and it seems that if i restart
the IPSEC service on the workstations, it relieves the
problem. We have also had problems with slow logins, and
inability to login except upon a reboot.
Could anyone speculate as to why restartign IPSec would
solve this problem and how to avoid it in general?
 
Hello,

Are your DNS servers also Domain Controllers? If so the communication
between DC's and clients will not be stable. Microsoft does not support
IPsec communication between Domain Controllers and any Non-domain
controller. Using IP Security (IPSec) to protect traffic from a
non-trusted domain member to the domain controller is currently not
supported when the policies are to be applied through Group Policy objects
(GPOs), or when Kerberos is the authentication method. This is because
non-domain computers cannot obtain the initial IPSec policy from the domain
controller, or for Kerberos authentication to occur with non-trusted
Kerberos tickets.

This would also explain some of the other errors you are getting.
