When you download an update from a WSUS server on Windows XP, the update fails. A red X is displayed near the update and you receive error code 0x80070002.

This behavior will occur if the Domain registry entry is missing from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters on the Windows XP computer.

To fix this problem:

01. Open a CMD.EXE window.

02. Type the following commands and pressing Enter after each line:

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /V Domain /T REG_SZ /F /D "%USERDNSDOMAIN%"
Net Stop WUAUSERV
Net Start WUAUSERV

03. Type ncpa.cpl and press Enter.

04. Right-click the Network Connection that you are using, like Local Area Connection and press Properties.

05. Double-click Internet Protocol (TCP/IP).

06. Press the Advanced button.

07. Select the DNS tab.

08. Type the DNS suffix, like JSIINC.COM, into the DNS suffix for this connection box.

09. Press OK, OK, and OK.

10. Close Network Connections.
