Windows 7 w/D0-06DR & H0-ECOM100 Comm Link Issue

[brian101]

All was working fine and then I lost connection. I am using Direct Soft 5.3.194 w/ a good crossover cable connecting to a H0-ECOM100 in a D0-06DR. All hardware work on my XPPro box just fine...
On my Windows7 box, I can see the H0-ECOM100 it in Netedit 3 and even write to its ip 10.11.11.50 & 255.255.224.0 and scan and find D0-06 every time. I just can't add a link to connect to the plc. I don't see any plc in the module list to connect to. I can ping the address, write to the card in netedit, and communicate (connect to the plc) through a USB to Serial in port 1 (C-more Micro programming cable). My network card is enabled and working properly, configured TCP/IPv4 10.11.11.80 & 255.255.224.0 and nothing (I can write to it in netedit). I have turned off my wirless connection and dissabled all network firewall and still nothing. This seems like it is a windows setting problem. It had been working just fine before this. The program quit responding and that's when all of this happened. 

I have also tried to connect through Link Editor. I get an error connecting to plc or defined link failed to communicate. I have had the same problem on my XP box in the past, because I was not on the same network address which points to windows 7 settings. I could see it in Netedit but not communicate. I am new to windows 7 but address is address if I am doing it right? I open network sharing center, select local area connection, then Properties, select TCP/IPv4, then Properties, and (select) enter proper ip address & subnet then click ok. I can then run ipconfig to confirm.

I have even tried rebooting with assign IP automatically and ECOM-100 addressed and hoping that Windows is smart enought to see the network connection and put in all the right stuff, but that doesn't do it either. I have also tried a combination of ipconfig /release and renew with still no luck. I am almost ready to send for a recovery cd and format my machine to start over, but the same thing may happen again or it still may not communicate. I would also like to be able to control my machine and know the cause.
What can I possibly try next? Can anyone please help
Thank's

Found the problem. The free uninstalled 60 day version of Mc Afee's was blocking traffic. I uninstalled all of Mc Afee's and as soon as I opened DS5 to add an ethernet link, There it was, Mac/IP address under module list. All works fine

Thanks for all views and your response(franji1). I hope this helps someone else save alittle time in the fuiture...

McAfee blows, almost as bad as Norton.  Try Avast for antivirus and Zone Alarm for firewall.
