You may pimp up your own approach by adding an address specification. Be aware that it will NOT change the third field if that doesn't contain 165, or change any other field that holds that value.

Code:
sed -r '/([^|]*\|){4}[^|]*1111\|/ s/\|165\|/|server1|/' file

EDIT: If you want to replace field 3 regardless of its contents, try

Code:
sed -r '/([^|]*\|){4}[^|]*1111\|/ s/(([^|]*\|){2})[^|]*\|/\1server1|/' file


P.S.: you might want to adapt the title of your thread.

LEARN ABOUT FREEBSD

colrm

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME

     colrm -- remove columns from a file

SYNOPSIS

     colrm [start [stop]]

DESCRIPTION

     The colrm utility removes selected columns from the lines of a file.  A column is defined as a single character in a line.  Input is read
     from the standard input.  Output is written to the standard output.

     If only the start column is specified, columns numbered less than the start column will be written.  If both start and stop columns are spec-
     ified, columns numbered less than the start column or greater than the stop column will be written.  Column numbering starts with one, not
     zero.

     Tab characters increment the column count to the next multiple of eight.  Backspace characters decrement the column count by one.

ENVIRONMENT

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).

EXIT STATUS

     The colrm utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     awk(1), column(1), cut(1), paste(1)

HISTORY

     The colrm command appeared in 3.0BSD.
