Hello.
Recently I started having some problems with f-secure. Problems started when I couldn't log into Policy Manager Console. FSPMC said that credentials for my user was invalid. At first I thought that 2nd Administrator changed password but he didn't. Additionally I checked Status Monitor. It showed my this:

Before I did address the blocked ports I did stop FSPM services and used "reset-admin-account.bat". Then I started services and I was able to log on. Afterwards I did opened ports (2221-2223 443; previously I did have only 2221 for hosts) on firewall and clients started to reconnecting to FSPM. I was thinking that my problem was fixed.
Few days later FSPMC served me another error about my user credentials. The only thing I did is restarting FSPM services and voila my account credentials were valid. Status monitor still shows the same errors (in fact screen capture above was taken few minutes ago but I remember it showing the same errors before opening ports on firewall).
P.S. In steps of fixing FSPM I did restart my system and also restored database from backup dating before I had this problem.
P.P.S. Today I had to restart FSPM 3 times.
