Captaris FaxPress Supplementary Manual page 24

Manage the FaxPress the same way you manage the other servers in your environment.
The company policy for hot fixes should also apply to the FaxPress. Be aware, however,
that some hot fixes may be incompatible with normal FaxPress function on a case by case
basis. For example, some security hot fixes may disable network ports needed by the
FaxPress, or change the system Print spooler to a setting other than autostart. These
specific changes are examples of the kinds of security fixes incompatible with normal
FaxPress operation.
Configuration Recommendations
Installing antivirus software on the FaxPress server with full file scan enabled is not
recommended. This will degrade fax server performance. When configuring antivirus
software on the FaxPress, be sure to exclude the following directories from On Access or
Real Time scanning:
Exclude the c:\Castelle directory (and sub-directories) on the FaxPress from On
Access or Real Time scanning. Schedule these directories for a Periodic scan to
be run during off-peak hours.
Exclude the c:\Fax and c:\windows\system32 directories on the FaxPress from
On Access or Real Time scanning. Schedule these directories for a Periodic scan
to be run during off-peak hours.
Exclude the C:\pagefile.sys paging file from On Access or Real Time scanning.
This files is typically a hidden, protected operating system file.
Any antivirus software used should also be configured not to disable network ports. The
FaxPress uses DCOM, for example, in load balancing configurations. DCOM listens on
dynamic ports. The FaxPress listens on the following static ports, which should not be
disabled:
25 - SMTP (email gateway)
139 - NetBIOS Session Service (Print Spooler, Drop directory)
443 - https (Web Client, Web Services SDK)
445 - SMB (Print spooler, Drop Directory)
Although installing antivirus software is recommended, the FaxPress should be closely
monitored for changes in performance after adding the antivirus software. Changes in
performance as the result of running antivirus software on the FaxPress include the
following:
CPU Utilization jumps to 100% and stays there. In most cases, this can be resolved
by excluding the c:\Castelle directory (and sub-directories) on the FaxPress from On
Access or Real Time scanning, as noted above.
The FaxPress no longer appears in the FaxPress Accounts dialog box of the
FaxPress client. This is due to a blocked port on the FaxPress. This can be resolved
manually by adding the FaxPress to the FaxPress Accounts using the TCP/IP
Advanced option and specifying the Name/IP address of the FaxPress server. (See
Locating a Remote FaxPress Server on page 76 for more information.)
With regard to Microsoft Service Pack updates, Captaris recommends applying the latest
Service Packs to FaxPress. Captaris applies the latest Service Pack to the FaxPress at the
time the HDD image is created. This means the FaxPress server ships with a relatively new
