PRB: Error C00E0521 "Unable to initialize the RPC library" at the End of MSMQ Install (263136)
The information in this article applies to:
- Microsoft Message Queue Server (MSMQ) 1.0
This article was previously published under Q263136 SYMPTOMS
An error message appears at the end of the Microsoft Message Queue (MSMQ) installation process while the MSMQ service is being configured:
"Unable to obtain computer properties from the information server.
Cannot initialize the RPC library.
Error code 0xC00E0521"
CAUSE
This error is usually caused by a misconfiguration of a computer's RPC settings. The MSMQ installer uses Remote Procedure Calls (RPC) to register itself with the MSMQ server and to replicate information between computers.
A computer that is functioning correctly will have a ClientProtocols registry key that resembles the following:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\ClientProtocols]
"ncacn_np"="rpcltc1.dll"
"ncalrpc"="ncalrpc"
"ncacn_ip_tcp"="RpcLtCcm.Dll"
"ncadg_ip_udp"="RpcLtCcm.Dll"
"ncacn_nb_tcp"="rpcltccm.dll"
"ncadg_mq"="RpcMqCl.Dll"
"ncacn_http"="rpcltccm.dll"
The following registry entries have been found to be missing on systems that exhibit this behavior:
"ncadg_ip_udp"="RpcLtCcm.Dll"
"ncacn_nb_tcp"="rpcltccm.dll"RESOLUTION
The only known resolution to this issue is to uninstall the TCP/IP protocol and then reinstall the protocol. To do this, follow the steps in the following article in the Microsoft Knowledge Base:

STATUS
