For, Notes 10, after the Notes Client displays the welcome page,
users are prompted by Windows Advanced Firewall to allow Communication for notes2.exe.
However many general users do not have the appropriate permission to Allow the requested action. They can only cancel the request. As a result from this Notes Client stops working with Message "waiting for application notes2.exe to respond".
Users Need to restart the Client.
After Restarting the client, it works normally
This occurs when two Inbound rules have been added to the local Firewall for the application notes2.exe located in NotesBinDr\framework\rcp\eclipse\plugins\[Release]\win32\bin folder.
One for inbound TCP and another for inbound UDP.
Both rules are set to block any traffic.
The Workaround being used in some cases is as follows:
Open an administrative command prompted to add rules using netsh command.
Step 1 - Delete any existing rule for notes2.exe
netsh advfirewall firewall delete rule name="notes2"
Step 2 - Add Inbound TCP Rule
netsh advfirewall firewall add rule name="notes2" dir=in action=allow protocol=TCP program="%programfiles(x86)%\IBM\Notes\framework\rcp\eclipse\plugins\com.ibm.rcp.base_10.0.0.20190213-0607\win32\x86\notes2.exe" profile=domain enable=yes
Step 3 - Add Inbound UDP Rule
netsh advfirewall firewall add rule name="notes2" dir=in action=allow protocol=UDP program="%programfiles(x86)%\IBM\Notes\framework\rcp\eclipse\plugins\com.ibm.rcp.base_10.0.0.20190213-0607\win32\x86\notes2.exe" profile=domain enable=yes
However this should be seamlessly handled by the Client Installation process.
