ADS Error 6420 on MS Server 2008

[unixkd]

Hi Roger

I have a client with server 2003 running ADS fine. Now they aquired server 2008 and could no longer connect to ADS. The application gives error 6420. We had tried all option enumerated in ADS documentation, no success, any help please ?

6420 indicates a upd communication error...

Make sure port 6262 is open on the server.

download udptester from the ads site.

If they get a 7000 series error after that, they forgot to shut off the old ads server..

lastly, only version 10 is certified to work on a w2k8..

Bobby Drakos and I had this problem recently and found out that the version was important. You need to upgrade to 10.0 for sure. Also, putting LAN_IP and LAN_PORT in your ADS.INI file may be necessary.

We use ADS Version 10 on a win2008R2 server providing RDP services for all users (which is where our applications resides) connection to another Win2008R2 server running ADS Version 10. I have found that the lan port and lan IP address are absolutely necessary. Otherwise our application could not find the server even when the ADS Data Architect application could.

Do you specify the Lan Port and LAN IP address in the ADS.INI file or through advantage configuration utility. If via ads.ini candly favor me with the content of your own ads.ini

Thanks

Note: RDH2 is the name of the computer hosting the ADS server version 10.x
The ADS.ini file is contained in the same directory as the program files, which are in a different directory than the database files.

I was working with a customer today who got the 6420 problem on a new installation.

I found that this was the only solution that would work. Chris Franz posted this on his website back in 2008.

I wrote an article on troubleshooting Advantage connection issues which details the discovery process. However, the discovery process can be avoided by changing your connection string or by specifying details in the ADS.INI file. By specifying a port number in the connection string the Advantage communication layer will not try to discover the server instead it will attempt direct communication to the specified server on the specified port. The following data paths would make a direct connection to Advantage without any discovery.

\\Server:6262\Data\MyDictionary.add
