this morning I logged the network activity
[9.02.21 RVP] Z:\tmp\miranda\miranda\src\modules\netlib\netlibop enconn.c 39: gethostbyname() failed (11001)
It looks like RVP error 4 comes out because the server name is not resolved...
Infact I noticed that in the configuration there is no OUTLOOK server name, how does the pluging guesses it ?

If your login is [email protected] then im.company.com is used as Exchange server name.Originally Posted by benny59

however, Windows Messaging works correct and uses right server.
and there are no im.company.com server in our network. It seems to be WM using another method to locate RVP server. And i have no ideas what this method is :-(
Also is such error code ( Error 4 ) correct for this situation ? Can you generate more readable error message? for example, which host it was trying to resolve ?
//sorry for my english and thanx for developing such greate plugin :-)

so ask your network/Exchange administrator what the Exchange server IP address is and then add it to your hosts.

Done,
I inserted the entry in the drivers/etc/hosts table.
Now I got the following log:

I have try it and find some problem.
When I try to login, the RVP try to contact one of the web server inside my company, but that web server redirect me to another web server.
It seems to be fine, but I find that, when it contact the first web server, it try to load a URL that contain my correct login name. But when it redirect to the second web server, it also try to load a URL that contain someone's login name, which is wrong, and that login name keep changing when I try it time by time. Seems that some buffer overflow problem there.

I'm getting similar results to Benny59 now. I've addressed the name resolution issue by creating a HOSTS file entry. However, we don't have a server named "im.companyname.com", so the IM server seems to think it's being passed a request for a Virtual Server:

We have a complex domain structure that the plugin is turning in to "im.<servername>.<sub domain>.<corporate domain>.com". I would think it would be a fix for all of these issues to just add a dialog box where we can type in the server name or IP address.

Thanks for the detailed information, but I need some more details regarding your network settings:
1) what would the correct Host (Virtual server) look like
2) what is the correct RVP-From-Principal ? Is the one generated by the plugin correct ?
3) what is the address of the Exchange server ? Is it the same as Host ?

some ideas about how to locate RVP server
1) resolve im.company.com
2) DNS query for _rvp._tcp service record
3) query ActiveDirectory via LDAP protocol
WinMessenger definitly makes (2) and (3). It loads DNSAPI.dll for (2) and WLDAP32.dll for (3).
Also AD can contain correct RVP Virtual server URL but i have no tools to explore AD structure :-(
i have no enough rights to edit HOSTS file :-( Can you complile debug version of plugin where we can manually change all params (host IP, VHost URL, Principal URL, ...)
