Impersonation between different workgroups is failed

[l-touched]

Hello,

I have 2 servers disposed in following manner

..- One IIS server (Named IIS-Svr), with a firewall for the Internet output (this server has his own valid IP for Internet), isolated in a Workgroup
(Win2003 Web Server, .NET Framework 1.1, IIS 6.0, ASPX pages, COM+ Applications proxies)

..- One COM+ server (Named COM-Svr), isolated in a Workgroup
(Win2000 Advanced Server, .NET Framework 1.0, COM+ Applications)

ISS server is isolated in a workgroup named WG-ISS, I have a user named UsuarioIIS in this machine, COM+ Server is isolated in another workgroup named WG-COM, I have a user named UsuarioCOM in this machine

Both of them are in the same network segment, they can connecting between themselves, although they are in differents Workgroup

Internet <-> Firewall <-> ISS <-> COM

Ok, like you can appreciate, I am programming in “n� tiers model, I have my bussines rules in COM+ server and my front end code in ASPX pages

Ok, actually, in developing environment I have both servers in the same Domain, the inpersonation is working very well

::Web.config:
<configuration><system.web><identit
impersonate="true
userName="Domain\UserName
password=" Password
/ ></system.web></configuration

But, when I going to production environment explode a fail because both of them not are in the same domain, are in differents Workgroups

Remember

Internet <-> Firewall <-> ISS (Named IIS-Svr in WG-ISS ) <-> COM+ (Named COM-Svr, in WG-COM

In my web application configuration (In IIS Server), I Tried this

::Web.config:
<configuration><system.web><identit
impersonate="true
userName="COM-Svr\UsuarioCOM"  NameMachine\Use
password="Password
/ ></system.web></configuration

But the following error appear

Server Error in '/WebApp' Application

Could someone help me please

I don’t know if I have to change special something in some of severs, or add something to my Config Web application files, or using another method for getting the same result

Perphaps this problem has a easy solution, but I haven´t any idea. Maybe using delegate and not inpersonation is better... I don'nt know..

Thanks in advance
