mirroring

I have 2 servers srv-erp1 and srv-erp3. I made them mirror on each other. All setup is done by lots of tutorials and examples.

But when I call

ALTER DATABASE MIRROR_TEST SET PARTNER = 'TCP://srv-erp3:5022'

It`s response is:

The server network address "TCP://srv-erp3:5022" can not be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational.

I go to cmd on srv-erp3 and use netstat -an... this port is listening.
I go to cmd on srv-erp1 and use telnet srv-erp3 5022...and its ok to connect.

All firewalls are turned off. The only difference in config of srvrs is that srv-erp1 is on Windows Server 2003 R2 x64, and srv-erp3 is on Windows 2008 R2 x64

What can be the reason of this problem?

Regards, Dmitry.
