The DCOMCNFG utility writes the port range specified for a protocol in a incorrect format.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
When a port range is specified for a protocol, such as 4000-4010, the value that is written to the registry key HKLM\SOFTWARE\Microsoft\RPC\Internet\Ports (named REG_MULTI_SZ) is "4000 - 4010." A space is added preceding and succeeding the "-". Remote Procedure Call (RPC) is extremly sensitive about the string format and fails the RpcServerUsePortSeq call with RPC_S_OUT_OF_RESOURCES. As a result, no client can talk to the server, and services such as Internet Information Server (IIS) do not start.
