I'm using ipmiutil.exe to reset the IPMI watchdog on my 64-bit Supermicro server (X11SBA-F) running Windows 10 Enterprise IOT, but it's not working returning the following error:

ipmiutil wdt -r
ipmiutil wdt ver 3.13

ipmiutil wdt, Invalid Session Handle or Empty Buffer 

I installed Intel IMB Driver downloaded from this link and tried both 32-bit and 64-bit versions of ipmiutil.exe but to no avail. Has anyone faced a similar error?

UPDATE 1:

I tried disabling Windows IPMI driver ipmidrv.sys but it don't help. On further tests, I noticed that after enabling IPMI watchdog through BIOS, it still shows "Watchdog timer is stopped for use with reserved." when I issue "ipmiutil wdt". It appears that ipmituil is unable to obtain the correct setting on the watchdog.

Here's some more information:

ipmiutil health, completed successfully

I found the solution. The problem had nothing to do with intel imb driver or 32bit/64bit. Enabling watchdog in bios is not sufficient. I had to enable it using ipmiutil:

ipmiutil wdt -e
