Have run into problems reinstalling SXTSQ lite5. Have 2 pcs.
The first one of them pings and there is a login page available in the browser, but it won’t accept login as administrator no matter you enter any password or not.
The second one isn’t pinging.
None of them would appear as devices in NetInstall after applying power while holding the reset button for 20 secs.
I guess only advice is to keep trying with netinstall. Netinstall process is highly fragile and you have to observe all requirenents as set forth in netinstall manual. Often the cause of faling to do process correctly lies in (slightly) incompatible hardware and settings of PC used in the process. You might want to try using different machine, OS, NIC or all of them. Or different version of netinstall.
