We are experiencing the following error:

This error usually means that PostgreSQL's request for a shared
memory segment exceeded available memory or swap space.
To reduce the request size (currently 2048000 bytes), reduce
PostgreSQL's shared_buffers parameter (currently 100) and/or
its max_connections parameter (currently 50).

The PostgreSQL Administrator's Guide contains more information about
shared memory configuration.
--> End log file

Could this error be related to file permissions and / or NT security? The reason I am asking is because the error only
appearsto occur when the NT server is on a domain, when it is off a domain the error does not occur. 

Does NTSEC have a bearing on pgsql-cygwin, should it be turned on/off when running cygwin?

Does NTEA have a bearing on pgsql-cygwin, should it be turned on on/off when running cygwin?
