Failed to ping or bind to the Infrastructure Master FSMO role holder

I have this error in scom

"Failed to ping or bind to the Infrastructure Master FSMO role holder"

I searched in the internet to know this error but I didn't know what to do .

I just found a link"http://mpwiki.viacode.com/default.aspx?g=posts&t=2053" that states I should open  the AD MP Events view.

I read the management pack of the active directory in this site :
http://technet.microsoft.com/en-us/library/cc180912.aspx

I found the following but that didn't help me

Syed_M_UsmanSystem AdministratorCommented:
your FSMO holder is up and running.
you dont have any replication issues.

with regards to dcdiag i already replied you.

regards to your question plz try to trouble shot DC connectivity, i would like to know is there any firewall between two dc's?

i tried to simulate your error in my LAB this comes when a firewall preventing ICMP packets. in my case this error comes on NON FSMO HOLDER, please confirm where you see this error? on fsmo holder or non fsmo holder...
omzeyadAuthor Commented:
I appreciate your support

I will ask the infrastructure department because they are responsible for the firewall,
I think this is the case ,because this error sometimes happened not always .

the windows  firewall is already closed

do you think that I must install Microsoft network monitor on the domain controller to see what happened in network ,would that affect the performance of the domain controller
Syed_M_UsmanSystem AdministratorCommented:
1) Win 2008 has three levels of firewall, i would suggest you turn on firewall for Public and Private networks...

2) could you please confirm where you recives this error? on DC1 or Dc2

3) WHAT TYPE OF  FIREWALL YOU ARE USING, plz tell me the model and brand

please draw connection typlogy between two Dc's

all I know that fortigate is used ,and all servers are located in vlan1 and workstation are located in vlan2  ,I'm sure that dc and adc are in the same vlan .no firewall between them

I think that may be the infrastructure department edit some rules and cause that error to generate ,therefore I need to install a network monitoring tool to know what happened but I'm afraid that  it may affect the performance of the domain ,I can't make the monitor record all connections  until a problem happened and I don't know when it will happen.
