I'm not seeing any activity tied to a specific account. I believe "servicio de red" is equivalent to NETWORK SERVICE which is not a username that OPL would be connecting with.
On my system, a successful OPL session logs the top three events seen in the picture I posted earlier. The user name column was censored in my pic, but it should be "X" "X" "SYSTEM" (from top to bottom) for those three events, where "X" is the username specified in OPL's settings. The events are (from top to bottom): 540 576 680, but I'm only seeing the Privilege Use event in your log, and it's tied to NETWORK SERVICE instead of a real account.
Now that I think about, those NETWORK SERVICE events are probably just noise; I saw a few in my log not long after clearing it, but never again during OPL operation. You should be seeing an account name, and the details will have your PS2's IP address in there somewhere for 540 and 680 events.
So I think your PC isn't even seeing a logon attempt. Perhaps something is going wrong before OPL can even attempt to log in. Maybe your file sharing subsystem is messed up or being interfered with somehow.
Make sure you're logging both successes and failures. Try disabling firewalls. Keep monitoring the log and look at that picture to see what you're looking for. If you see some real logon attempts, then you're on the right track.
Type the following at a command prompt:
netstat -a -n
You should see the following line somewhere if sharing is active.
TCP 0.0.0.0:445 0.0.0.0:0 LISTENING
OK, good! I can see your PS2 logging in as a Guest (ANONYMOUS LOGON) now, so that part seems to be working. Did you change something?
The problem might have to do with the share itself. Make sure it is properly shared and that permissions are set up correctly.
For now, move everything out of the share folder; OPL (0.9) will still connect even if the share is empty, and it will even create empty VMC and CFG folders. Play around with the shared folder's settings until error 300 goes away.

Not sure what to make of that picture. It looks like a bad username, but it might just be some random network garbage. If you scroll down in the properties window it should show the IP address in "Source Workstation" field of the 680 event, to check if it really is your PS2.
If you feel like it, post pics of your share folder's Sharing Tab (and the Permissions button) and Security Tab in the properties dialog for analysis.
I really can't think of anything else to try right now. I'm going to bed.
I have the same problem. Error 300 with everything configured, FW ports opened on router and windows, Windows 7 shared folder ok and i can ping the PS2. But it dont connect.
Maybe i have disabled some windows sharing service, dont know.
Edit: Nevermind, i created a new account in PC and login with that, instead of Everyone, works ok. Oh, and the DVD subfolder, it took me a while to figure out.
