My install of SFU was working great for a couple of weeks, now I get the following in the event log:
Could not connect to Mapping Server at host localhost:while connecting :
RPC: Port mapper failure - RPC: Unable to receive
Any help?

Which ports should I be looking at? Are we talking the Microsoft RPC ports?

There should be output from netstat for both TCP and UDP
that has a label or part of a label that has "rpc" in it, or
are port 111 (TCP & UDP).

Rodney is correct, such an error usually means something like blaster worm
W32.Blaster.Worm is a worm that exploits the DCOM RPC vulnerability (first described in Microsoft Security Bulletin MS03-026)(users are recommended to patch this vulnerability by applying Microsoft Security Bulletin MS03-039) using TCP port 135. The worm targets only Windows 2000 and Windows XP machines. While Windows NT and Windows 2003 Server machines are vulnerable to the aforementioned exploit (if not properly patched), the worm is not coded to replicate to those systems. This worm attempts to download the msblast.exe file to the %WinDir%\system32 directory and then execute it. W32.Blaster.Worm does not have a mass-mailing functionality.
Additional information and an alternate site from which to download the Microsoft patch is available in the Microsoft article, "What You Should Know About the Blaster Worm and Its Variants."
We recommend that you block access to TCP port 4444 at the firewall level, and then block the following ports, if you do not use the following applications:
TCP Port 135, "DCOM RPC"
UDP Port 69, "TFTP"
The worm also attempts to perform a Denial of Service (DoS) on the Microsoft Windows Update Web server (windowsupdate.com). This is an attempt to prevent you from applying a patch on your computer against the DCOM RPC vulnerability.
Click here for more information on the vulnerability that this worm exploits, and to find out which Symantec products can help mitigate risks from this vulnerability.
NOTE: Virus definitions will detect this threat having:
Defs Version: 50811s
Sequence Number: 24254
Extended Version: 8/11/2003, rev. 19
Symantec Security Response has developed a removal tool to clean the infections of W32.Blaster.Worm.

Hi!
I have the same problem on some machines. It is a standard unattended installation.
No additional software installed and no changed configuration settings.
Maybe it is a port number used by another process? But i have no idea wich port number...
Which port numbers are used by SFU? (Default settings)
When i start the C Shell i get an error message:
=============================================================
WARNING: One or more events have been logged in the Event Log
that the system administrator should investigate.
=============================================================

You get this warning if the file /var/adm/SystemWarning exists.
The event log you refer to (Mapping Server) is not an event that would cause
the SystemWarning file to be created.
You should be looking for an event generated by the Interix subsystem.
Normally this warning file is created when the Interix subsystem cannot
resolve a uid or gid from the Windows' SecurityID.

I see this happen once in a while (I have one domain and 6 machines).
Not very often. Maybe twice a year.
Not often enough for me to try to track down the reason for
the event log entry.
I just remove the SystemWarning file and continue.

I also consistently at startup get in event viewer (application):
Interix error:
Could not connect to Mapping Server at host localhost:
while connecting : RPC: Port mapper failure - RPC: Unable to receive
no blaster worm with symantec scan
XP-SP2 (no need for blasterworm patch)
any ideas?

So you're using the Username Mapping (UNM) I assume for NFS.
Is/are the NFS mounted drive(s) showing working okay?
I'm wondering that if it manages to connect later, quietly, and things are
working that you can ignore the message.

Everything seems to be working allright.
No files or drives are unavailable.
Just noticed this error in the event log.
