Filers disconnecting from DC--CIFS shares issue

[raovolvoadmin]

HI All,

we have many filers which are running from 7.2.3 and below.AD team upgrading the Domain controllers from the win2000 to win2008.Due to that filers which are running on 7.2.3  and below not able to connect to DC.Is this bug in older ontap versions?.Do we have any workaround for this issue?.

Thanks in advance..

Unfortunately the IMT (support matrix) for 7.2.3 only lists 2000 and 2003.  Does anyone know of a way to have 2008 work in backward compatibility?  The best thing to do is likely upgrade to the latest 7.3 on all systems... or at least a higher 7.2.6 which looks like it supports some 2008.

Microsoft Windows 2000 Server (SP4) Microsoft Windows Server 2003 EE (SP2 32-bit, x86) Microsoft Windows Server 2003 R2 EE (32-bit, x86) Microsoft Windows Server 2003 R2 EE (64-bit, x64)
