have you ever experienced any unsuccessful installing of ePO server with v4.5? i think it always has more or less. Once you installed SQL server incorrectly, it will appear the case of the ePO server can't detect the SQL Server when you carry out the installing. perhaps it is the other situation that you uninstalled the ePO server and planned to reinstall it. Unfortunately, you encountered the trouble of that i mentioned. Next, i will introduce how to solve this issue.
It is straightforward to come to this step when you intall the ePO server. However there is no any Database Server appearing in the scroll list.
Open SQL Server Manager, and lookup the SQL service instance, such as AVSVR\EPO, enter it.
The ePO installing process is detecting the provided information.
But it is worse and report an error subsequently. You have already had no way to execute the coming steps. According to the prompted message, you input the SQL UDP port 1434 in the "SQL server TCP port" filed in setup. However, the issue still exists.
Don't worry, and Open SQL Server manager, and extend Network Protocols, and right click on TCP/IP Properties, switch to IP Addresses lable. Go to the bottom, check and remember the TCP Dynamic Ports( here is 1129)
Key in SQL server TCP port as 1129. Click Next.
It's pleasing, and going on the next step smoothly, so complete the left steps of installing ePO server can be predictable.
Okay, now the problem is addressed.
