Untrue (?): “The RPC server is unavailable.”

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I'm developing a kind of Intranet"Remote Computer Monitor" C# application for

1. Windows Logs monitoring,
2. Processes monitoring,
3. Performance monitoring.


Environment:
- Application (local) PC - XP, SP2, VS2003.
- Remote PC - Windows Server 2003.
- IIS 5.1 on local PC (IISADMIN service is running)
- Administrator account on local PC and Administrator account credentials
for Remote PC are
used.
- All Windows Services related to Remoting on both local and remote PC are
Started
- "System.Management" namespace in used.
- tcp port 135 is open (I even disabled Windows Firewall for a while – not
very dangerous in
Intranet)
-
- All Settings for Visul Studio Remote Debugging are implemented.

=--------

“Windows Logs monitoring” and “Processes monitoring” are OK
(Impersonalization works), but
“Performance monitoring” part returns an error
"System.Runtime.InteropServices.COMException (0x800706BA): The RPC server is
unavailable."
System Event Log shows:
“DCOM was unable to communicate with the computer “Computer Name” using any
of the configured protocols.”

Previous System event (on Remove machite too!):
“The WMI Performance Adapter service entered the running state.”

----- -----
Source code for the critical part:

string computerName = Dns.Resolve(computerIP).HostName; // computerIP
direct use causes “Access Denied” message
ManagementPath path = new
ManagementPath(String.Format("\\\\{0}\\root\\cimv2",computerName));
// Or like this => "\\\\" + computerName + "\\root\\cimv2

ConnectionOptions options = new ConnectionOptions();

options.Authentication = AuthenticationLevel.Packet;
options.Username = userName; //checked domain\user format too
options.Password = password;

_searchScope = new ManagementScope(path, options);

--- ---


Then I checked whether RPC server is really unavailable.

I added myself (my local PC user name and pwd) to remote PC as a member of
Administrators Group, then opened Windows Performance -> System Monitor on my
local PC and connected to a remote one.

Everything is excellent - I see all the Graphs, I can add any Counter I
need. Works fine with or without Firewall activatede.

So RPC Server IS working, I guess. What the problem is????

Please Help!!!!!
