Hello
It took a while until I was able to get the logs from a failed machine. There have been three occasions been logged where the client updated the AD Password. Both
2022-5-23 and 2022-05-31 have been fine only 2022-06-07 wasn’t and locally the kvon was not updated, but on the DC it was. The only difference I can spot this.
Working:
* Found computer account for LC015564$ at: CN=LC015564,OU=Computer,OU=Minden,OU=Germany,DC=wago,DC=local
* Retrieved kvno '16' for computer account in directory: CN=LC015564,OU=Computer,OU=Minden,OU=Germany,DC=wago,DC=local
* Sending NetLogon ping to domain controller: svdc01011.wago.local
* Received NetLogon info from: SVDC01011.wago.local
* Changed computer password
* kvno incremented to 17
* Checking RestrictedKrbHost/lc015564.wago.local
Not working:
* Found computer account for LC015564$ at: CN=LC015564,OU=Computer,OU=Minden,OU=Germany,DC=wago,DC=local
* Retrieved kvno '17' for computer account in directory: CN=LC015564,OU=Computer,OU=Minden,OU=Germany,DC=wago,DC=local
* Sending NetLogon ping to domain controller: svdc03002.wago.local
* Found old kvno '17'
* Changed computer password
* Retrieved kvno '17' for computer account in directory: CN=LC015564,OU=Computer,OU=Minden,OU=Germany,DC=wago,DC=local
* Sending NetLogon ping to domain controller: svdc03002.wago.local

* Checking RestrictedKrbHost/lc015564.wago.local
I inclued all log output. To me it looks like the communication is done only in TCP allso I do not see any
KRB5KRB_AP_ERR_REPEAT errors. So I believe I have a different problem then Spike.
I do believe that the problem only occurs if the client is connect over VPN. But I have no data to prove this. It may also be related to the side the client is connected to. I have no idea what to check next. Maybe I
will set one specific server to be used for updating the computer password.
