SYMPTOMS
Distributed Component Object Model (DCOM) applications that connect to a Microsoft Windows 2000- and Microsoft Windows XP-based computer and are configured to use only datagram protocols receive the following error message:

Not enough storage is available to complete this operation(0x8007000e)

DCOM clients that are configured to use only datagram protocols that connect a Windows 2000 and Windows XP DCOM server receive the following error message:

The RPC Server is unavailable (Ox800706ba)

In addition, a message similar to the following appears in the Event Viewer: EventID:10009 Source:DCOM Type:Error Description:DCOM was unable to communicate with the computer Remote Server Name using any of the configured protocols To connect to a DCOM server on Windows 2000 and Windows XP, there must be at least one common connection-oriented protocol between the client and DCOM server.



CAUSE
Component Services Administrative tool or DCOMCNFG incorrectly allows you to add Datagram User Datagram Protocol/Internet Protocol (UDP/IP) and Datagram Internet packet exchange (IPX) protocols to the Default Protocols tab. Windows 2000 and Windows XP do not support any datagram protocols.

RESOLUTION
Make sure that connection-oriented protocols are in the DCOM protocols tab. Remove any of the Datagram protocols from DCOM protocols tab.
 * 1) Bring up the Component Services Administrative tool. On the Start menu, point to Programs, Administrative Tools, and then click Component Services.
 * 2) In the console tree of the Component Services Administrative tool, right-click the computer on which you want to configure the protocol, to bring up the context menu.
 * 3) Click the Properties menu to bring up Computer Properties dialog box.
 * 4) Click the Default Protocols tab.
 * 5) If you have any of the Datagram protocols (UDP/IP or IPX) protocols listed here, click to select, and then click Remove.
 * 6) If you do not have any of the connection-oriented protocols in the list, click Add to bring up Select DCOM protocol and endpoint dialog box.
 * 7) Choose Connection-oriented TCP/IP Protocol as the protocol sequence, and then click OK.
 * 8) Add any or all of the connection-oriented protocols to the default protocols this way.
 * 9) Move Connection-oriented TCP/IP Protocol to the top of the list.
 * 10) Restart the computer for the changes to take effect.
