LFDS-Adding/Modifying users, user gets EID:2 Socket errors

posted on July 10, 2020

Hello,

Customer relayed this message and error output:

When adding or modifying Laserfiche users (Not AD) in LFDS, the server logs multiple EID:2 Socket errors when using the web browser.  If I use the Laserfiche Administration Console, there are no errors generated.

System.Net.Sockets.SocketException (0x80004005): No such host is known

I am seeing the same issue in addition to an error (9528) when attempting to enumerate the user details from the repository.  We recently attempted to move our servers from one AD domain to another and stopped short when these errors started to appear in production which was still in the original domain as LFDS.   

With regards to the Laserfiche server app in the LFDS, does this refer to the server description in the register instances under the applications?

Hi Jeff,

Are you using the fully qualified domain name for your Laserfiche Server app instance in LFDS? It looks like the address lookup for the host name supplied is failing when LFDS tries to send notifications to LFS (LFDS notifies LFS about various changes to the licensing site and users if you have notifications turned on under advanced options).
