RE: WINS error 4204

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

No glory at this stage but still trying - I think it may be a network
appliance issue so I'll keep you posted

Hi Dave,

Thanks for posting here.

From your problem description, I understand this issue to be: the SBS
server is experiencing the following error on WINS: "Event ID: 4204 - WINS
could not read from the User Datagram Protocol (UDP) socket." These errors
occur every 40 minutes. If I am off base, please feel free to let me know.

I believe that this issue is the result of a destination host unreachable
message being sent in response the WINS service Automatic Partner
Configuration function. The default is for a multicast service announcement
to be sent out over the wire every 40 minutes. The feature is designed to
let the WINS servers announce themselves for automatic replication. The
idea is as an alternative to statically configured WINS replication
partnerships. Most people are not using this and your issue should be
easily resolvable with the following registry settings:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Parameters
Entry Value Name: UseSelfFndPnrs
Data type: REG_DWORD
Value: 0

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wins\Parameters
Entry Value Name: McastIntvl
Data type: REG_DWORD
Value: FFFFFFFF

Furthermore, there are also some cases that this issue is caused by Network
Appliance (unknown brand) send the ICMP Port Unreachable back to the server
from the IGMP (multicast) WINS packets. You could take these Network
Appliance offline to resolve this issue.

If you have any questions or concerns related to this issue, please let me
know.

Thanks and have a nice day.

Best Regards,

Steven Zhu
