I tested 3.050 ->3.052, and everything worked OK except, on Win 2k & Win 98 clients, Outlook Express generates an error message and cannot retrieve mail from my POP3 server (hotmail works OK), and Igloo FTP cannot establish a socket with any site. Both OE and Igloo work fine on my running 2.23 box, both before and after I try 3.05x on a test box.
The 3.05x box has a PIII 800 on a SE440BX board with 256mb RAM, and the 2.23 box has a Celeron 366 on a MU440EX board with 128mb RAM. The boxes use identical Realtek NICs.
I've fooled around with Astaro quite a bit, and tweaked just about everything I could think of in 3.05x without success re. POP and FTP.
Sure would appreciate any suggestions.
