Celerra NS500 support matrix

Hello,

we have this really old EMC BAY with SW version 5.5.22-2 where is CLARiiON CX500 behind, with Flare version 2.19.500.5.034.

As this BAY is already out of EMC support I wasn't able to find any documentation on EMC web pages. I tried google too, but without luck.

I am looking for some document or something where is described what is supported for the CIFS, if Active Directory / Domain Controller within the range of Win servers 2003 - 2012. As customer has problems on Domain Controller 2012, when turned back to 2003 everything was ok.

Thank you in advance
