Hyena very SLOW after 8.6C upgrade

[Guest]

I just upgraded to Hyena 8.6C and now it is unusably slow.... I was running 8.5.8.50.3000. Now double clicking on a domain user takes 10+ seconds to display attributes, Group display slow too.

Nothing changed from v8.5 (original release, not rev 'D'), except that we are now using more updated Microsoft libraries due to v8.5 'D' and later now being built on a newer version of Visual Studio.

What we have seen that can cause a slowdown is using a Netbios format for the LDAP path for the domain, instead of DNS. Check under File->Manage Object View to make sure the domain is using a fully qualified LDAP path like LDAP:\\mydomain.com and NOT LDAP:\\mydomain

Yeah, I saw that in another post and it's correct...

I'm running Win 7 64bit. Also getting that "Error getting terminal server data. The parameter is incorrect." when clicking on Terminal Tab. I was getting that before too.

I did just the opposite... Set it to netbios name and now it's snappy. Terminal Server Error went away too.

The terminal server error can usually be avoided by turning off the terminal server option under Tools->Settings->User.

If DNS is slow vs. Netbios, check the DNS name server or however that is setup. Most functions will work fine either way, but some AD functions work better using DNS. But it all depends on the environment.

OK, thought I had this solved, but this morning it was slow again. This time I noticed the domain controller Hyena selected. It choose a domain controller in another subnet across a wan link... So I specified a local DC and(using full FQDN LDAP Path) and its snappy again. I check my PC's LogonServer and indeed it is a local DC. I checked Sites and Services, networks all defined correctly, I checked AD replication and no error. So, I guess this brings me to my question. Why would Hyena choose a domain controller in a remote network over the same domain controller that authenticated me at logon?

Re: Hyena very SLOW after 8.6C upgrade

Hyena uses a Windows function (DsGetDcName) to get a name of a writable, directory-service enabled domain controller for a domain that does not have a specific DC specified for it. We have no easy control over the controller selected by this function, which is why we have the flexibility to allow you to set it.

Good catch though on finding this problem.

Re: Hyena very SLOW after 8.6C upgrade

Ok, I think I found a bug..
I have the same Domain listed in "Objects" twice. Domain X with NO ADSI server specified and the same domain Domain X (RemoteDC) with the ADSI Server specified. To solve the slowness problem I specified a local DC for the Domain X "Object". If I click on users hyena shows pulls from the specified DC. However if I add new user and specify the OU from the Domain X "object" it uses the Remote DC's Path instead of the one specified for Domain X. Just for giggles, I moved the Domain X (Remote DC) below the Domain X in Object manager and it worked as expected.... I thought that’s odd. So I removed the ADSI Server Path from both Objects and what do you know Hyena picked the local DC... Maybe my situation is Odd, but when I'm in a hurry to create an account in the remote site and I don't want to wait for it to get replicated I use the Hyena Domain Object with the remote DC specified...letting replication happen when scheduled to other DCs. So their seems to be some disconnection when having a domain listed twice in objects and having 1 specifying a DC and the other just in theory choosing local dc... As well as order in the list. Let me know if this confuses you and I'll try to explain better.

To try and test this it would be best if you could send screenshots of how you have them configured in Object Manager to [email protected].

Re: Hyena very SLOW after 8.6C upgrade

Having the domain listed twice might be causing an issue, as when Hyena needs a DC for a domain, it will (for performance) check to see if the domain has already been manually added with a specified DC, and if so, it will use that DC. This lookup probably goes in order that the objects are listed.

Re: Hyena very SLOW after 8.6C upgrade

The lookup makes sense... I have had it this way for a long time and never had the problem before the upgrade. Is there any other suggestion for "quickly" selecting a domain controller without manually adding it to the domain object since duplicate domains is now a problem?

You can right-click on a domain and choose Set Source Domain Controller.

Re: Hyena very SLOW after 8.6C upgrade

ahh... I forgot that was there. It updates the ADSI Server path for the domain object. That works.
Thanks
