After booting from the Acronis boot cd Backup and Recovery 11 can not go to a network share windows 2008 r2, and Windows 7 are constantly requested username and password (login and password are correct.)
The level of authentication LanManager: send NTLMv2 response only to discard LM and NTLM
With this setup, authentication level in win XP to access network resources available.

If you disable NTLMv2 in Win7 is written in the logs that the authorization is for NTLMv1.
