Logmein Antivirus firewall blocking network printing
Has anyone else run into this and is there a way to resolve? We use IP based printing and after installing Logmein Antivirus (with firewall enabled in the policy), we've experienced issues with prin...
I had a problem with network printers also. It was only some of the locations we manage, not all.
To get ours to work, I tried some things: editing group policy AD (for domain computers) and local GP for non-domain. I added firewall rules into there for the IP ranges needed and ports etc.
I also realised the machines failing were on network connections set as "Public". I used a powershell script and the LMI One2Many feature to change all the network connections to "Private". This was only on the machines not on the AD domain. Luckily in our case, we name all the network adapters on machines the same "Broadband" because we have 2 network cards in use and need to differenciate.
Set-NetConnectionProfile -InterfaceAlias Broadband -NetworkCategory Private Set-NetConnectionProfile -InterfaceAlias OtherNetwork -NetworkCategory Private
After making these changes, it's all fine.
Not sure if the Windows Firewall Group Policy rules are having any effect though as LMI seems to manage to firewall. I could easily test by blocking something on GP and see if it takes effect.
Please note that we've found the reason of network printing being blocked by the LogMeIn AV Firewall.
We will add an option to the AV policy to enable network printing early next year.
When I run the command Get-NetConnectionProfile it shows the NetworkCategory = DomainAuthenticated and the DomainAuthenticationKind = Ldap.
If I try to run the commnand
Set-NetConnectionProfile -InterfaceAlias Wi-Fi -NetworkCategory Private
I get errors because it is a computer that is joined to our domain. So this does not resolve our issues.
Several users still can not print while on Wi-Fi, they get print errors. We have done everything possible to fix this. from removing drivers to checking subnets to accessing the printers web UI. Some people can print to the printer, so We know it is not a problem with the printer. (we only started having these problems after we installed the LMI suite)
Please help resolve this asap
Thank you
