Hi,
Administrators maintaining multiple SEPM's or security products have problem in resetting in SEPM 12.1.x is they have missed out to provide email address during installation.
resetpass.bat was present in 11.0.x and greatly missed in 12.1.x. i have re-constructed restpass.bat to reset password for 12.1.x SEPM.
Just like 11.0.x the resetpass.bat has to placed in the following location, unzip the file place in the location mentioned below.
For 32 bit:
Driver in which SEPM is installed/Program files/symantec/symantec endpoint protection manager/tools/
For 64 bit:
Driver in which SEPM is installed/Program files(x86)/symantec/symantec endpoint protection manager/tools/
Once it is placed in tools folder and run it with administrative privileges, then it will open a command prompt and close automatically it might take a couple of minutes, once the command prompt closes.
Open SEPM console and type
Username: admin
Password: admin
