SYMPTOMS
When you start a computer running Microsoft Windows NT 4.0 (Service Pack 4), the network services that Remote Procedure Call (RPC) enables may not start, and the following error message may appear:
Not enough resources are available to complete this operation.
The network services that may not start include, but are not limited to, the following:
- Domain Name Service (DNS)
- Dynamic Host Configuration Protocol (DHCP)
- Windows Internet Naming Service (WINS)
- World Wide Web (WWW) Publishing
- File Transfer Protocol (FTP) Publishing
- Network New Transfer Protocol (NNTP)
- Simple Mail Transport Protocol (SMTP)
Also, the System log in Event Viewer may record Events 4156, 453, 1006, 1008, and 7023.
CAUSE
This behavior can occur when there is a hyphen in a port range in Dcomcnfg. The system adds a space before and after the hyphen when it writes the port range to the registry, making (for example) the range 4000-4010 appear as 4000 - 4010. RPC does not recognize this string format and responds to the RpcServerUseProtseq call with RPC_S_OUT_OF_RESOURCES.
RESOLUTIONWARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
To work around this behavior, manually remove the extra spaces in the port range data:
- Use Registry Editor (Regedt32).
- Locate and select the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Internet\Ports
- In the right pane, double-click the Ports value.
- Delete the spaces immediately before and after the hyphen in the port range.
- Quit Registry Editor.
- Restart the computer.
