I assume you put in the enabler code but did you also put in the authorization code?

Expired or disabled?

If disabled than most likely your hostid is not the same.

If expired, then it was not authorized before and most probably something is not the same (hostid again?)

Hello
I restored the bootstrap so I think I do not have to re enter the licenses

I assume my hostid has changed since before the features were permanently licensed without expiration.
Now after OS reinstallation and Bootstrap restore it shows that license will expire in 13 days.
Have I to rehost ? Is there a way to change the hostId back?
I was told that We have right to rehost the server only 5 times

If you reinstalled to OS then the host ID will have changed as it is derieved from the SID number for Windows machines. You will need to get your enabler authorized against the new host ID and apply that and then you will be alright.

Is there any way to change the Hostid?

Yes, there is a tool from sysinternals to do that. But that's not something you should do - rather do host transfer to new hostid (but if I understood correctly, now everything is ok, right?)

No, things are not Ok I still have the message that the license will expire in 13 days".
I was told that we have right to only 5 rehost operations. we would like to preserve these retries since we have done it before and planning to migrate networker in the future again
.
Would you please tell me what is the sysinternal tool which helps me to change back the hostid?

hostid if based on SID on Windows - do some googling on it and you will easily find what you are looking for.

I never heard of that limit - make sure you check that. Actually, I believe that is crap. In theory you can have more than 5 DRs thus I see no point of such limit. OK, rehost is kind of different, but so what... license is license... I'm quite sure that is not correct would still go for "by the book" approach.

Could you please tell my I shouldn't change the hostid?
thank you

I've never heard of a limit to the number of re-hostings but I don't think there are many (any?) places I have seen who have had to re-host their Networker server that many times anyway. Plus if EMC do give you crap about licenses there are a few magic words like HDS, NetApps, Netbackup which should sort your account manager out

All you need to do is send an email to licensing@emc.com asking to move enabler xxxx-xxxx-xxxx-xxx to host ID xx-xx-xx ( you cqn find the host ID by going in the NMC GUI to Configuration > Licensing > Registrations and then looking at a license. Should take you the best part of a minute to sort out!

Can anyone tell me how to calculate the windows Hostid?
is there any formula?

You do not calculate hostid, it is system generated. You can find it in the GUI. See David's post above for the location.

Regards...

What happened is that we reinstalled windows two times for different reasons so we had to rehost the License. EMC support confirmed to me that we have only right to 5 rehost operations beyond that we have to pay some fees.
That is why I asked If it is possible to change the HostId instead of changing the license.
After that I am a little curious to learn how things work.
I did a lot of searches about this topic but couldn't find advanced docs
Thank you a lot for your kind help

The system generates it from the SID number of the Windows installation; if you have a UNIX / Linux system it is based on the MAC address of the system board. If these numbers change your host ID changes and thus your authorization code changes, but you shouldn't expect to see these change frequently!
The host ID used to be based on the IP address of the system and you still can do this (its something like the IP address expressed as hex backwards - there should be a technote in Powerlink) but why do something complicated that will confuse you and others down the line.
