SysAid - In RDS list, can not see the machine I have installed RDS software on

Problem: SysAid - In RDS list, can not see the machine I have installed RDS software on

Solution: On the machine I have installed RDS on, go to the folder -

C:\Program Files\SysAidRemoteDiscovery\root\WEF_INF\root, open the text file -

Discovery Services.properties

There are two lines containing the IP address of the SysAid server. The first one is with the port 8080, the second one without.

What we need to do is to just add ':8080' at the end of the second line of IP address.

Save it. Restart the RDS service.

Done.
