After upgrading to a new PC running Windows 7 Enterprise Edition 64 bit from Windows XP, which by the way connected to my MAC Server OSx 10.6.8 just fine, I can no longer connect to my MAC Server and get access to my drives.

Yes, I've read all the forums and have done the following From my Windows 7 PC:

1. Type Secpol.msc in start button.
2. Expand "Local Policies" and select "Security Options."
3. Alternate : Type secpol.msc to get editor up then
4. Locate "Network Security: LAN Manager Authentication Level" in the list and double-click it.
5. Change the setting from "Send NTMLv2 response only" to "Send LM & NTLM -use NTLMv2 session if negotiated" Apply & OK.
6. Then locate "Network Security: Minimum session security for NTLM SSP Based (including secure RPC) Clients."
7. Change the setting from "require 128 bit" to unchecked (No Minimum).
8. Click Apply and OK.

I can get this to work no problem if I don't authenticate to my Corporate domain which I have to.

If I logon to our Corporate domain, I cannot change this setting as its locked down via GPO.

I've talked with my Microsoft Engineers in house and they will not allow me to back these settings down because of the security vulnerability it poses once they relax this setting.

Is there anything else I can try so I can get this to work from my Windows 7 PC's?  I've tried looking for areas of registry hive entries that I can change and to no avail, I can't find anything.

Help!

I am afraid that there is nothing you can do as if "your Microsoft Engineers in house do l not allow me to back these settings down because of the security vulnerability it poses once they relax this setting", you cannot change the registry also as you need domain admin rights to change the registry which is corresponding to the change for the security policy.

Is your MAC server owned by you or the Corporation? If it is owned by your Corporation and is a MUST for your work to use the data in the MAC server, you can escalate the issue to the management of your Corporation to ask your Microsoft Engineers in house to make relevant changes for you as they can assign your domain user account to be "local administrator" account for changing the security policy just for your computer.
