Correct answer provided by Celerra community  Correct Answer by yikai on Jan 11, 2016 5:08 PM I think this is a Bug on file version 8.1 you can run command: $server_param server_2 -facility cifs -modify nullSession -value 2 then change your password server_param server_2 –facility cifs –modify nullSession –value 0
I have loaded the 8.1.8-37119 .ova file into VMware Workstation 12 Player  and set it to be 8 GB (2 DM sim.)  I've used unisphere to enables the licenses started the cifs server using server_setup server_2 -Protocol cifs -option start I used unisphere to enabled unicode for server_2 [IMAGE]  created an interface on server_2 [IMAGE]  created a standalone cifs server on server_2 using the configured I/F [IMAGE]  BUT...When I try to change the default Administrator password ( that I set when I created the cifs server) from my Windows box I get access denied.    I can't get a screen shot of that but the format is          \RBwin2016S\Administrator           nasadmin                         ..     spinning circle for about 15 seconds   access denied   I do the exact same steps using the 8.1.0-38015 .ova simulator and I have no problems changing the password or anything else.  Can someone please point out what I'm not doing correctly if anything & what I can do to get this to work.
VNX simulator 8.1.8-37119 won't allow me to change new cifs server password
