ADNM 4.8 Cannot find any computers

Hi,
I have recently purchased and installed ADNM 4.8 on our server (Windows server 2008). Have created the database and can login perfectly. When i go to server tasks and run the std discover computers task it does not find anything. I created a discover task to search for all computers on our network but don’t find anything. Not even the server ADNM is running on. There is no domain, just a windows workgroup. The firewall router is the DHCP server. Not to sure what other info i can give but i please need help on discovering computers on my network.

Thanks in advanced.

do you have the firewalls on the computers turned on?

if so thats highly probably the reason

since you dont have a domain directory where avast can search, it has to find the computers by the ip address, if the firewall blocks the requests that avast looks for then it will not be able to find the computers…
