DNS Update Fix for SBS 2003

Microsoft has updated the article on the DNS Update problem for SBS 2003.

I suggest you read the entire article at KB956189 before proceeding.

For myself I am putting the fix here were I can find it faster when I forget the kb number, but I have read the article, you should too.

Use at your own risk as always

RESOLUTION

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 (http://support.microsoft.com/kb/322756/) How to back up and restore the registry in Windows

To resolve this problem, add the port that is needed by the service to the ReservedPorts registry value. This prevents the DNS Server service from listening on that port. The following ports are known to cause conflicts:

Ports Program that uses the ports
1645-1646 IAS
1701-1701 L2TP
1718-1719 H.323 Gatekeeper (ISA 2000 only)
1745-1745 ISA Server 2000 or ISA Server 2004
1812-1813 IAS
2883-2883 AUTD
3500-3619 ISA Server 2000 only
4500-4500 IPSEC

To configure the ReservedPorts registry value, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then click the following subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3. Right-click ReservedPorts, and then click Modify.
4. Type the range of ports that you want to reserve.Notes

• You must type the range of ports in the following format:

xxxx-yyyy
• Do not replace the existing values. Instead, add the additional values.
• To specify a single port, use the same value for x and for y. For example, to specify port 4000, type 4000-4000.
• If you specify the continuous ports separately and if one port is reserved and is not used, the next port is not reserved correctly, and the port is used.
• ISA Server settings only apply to Small Business Server 2000 or to Windows Small Business Server 2003 Premium Edition.
5. Click OK.Note If you receive the following warning message, click OK

Warning:
Data of type REG_MULTI_SZ cannot contain empty strings.
Registry Editor will remove the empty string found.
6. Exit Registry Editor, and then restart the computer.

Notes

• You must restart the computer after you make these changes for the changes to take effect.
• If you are using any third-party applications on the server that might require you to use a static UDP port that is higher than port 1024, you should also add it to the list of reserved ports.
