|The essential or critical point in the original message relates to the IAS databases.|
The statement that followed the main matter, "Proper setup of TCP/IP and NW Link IPX/SPX/NetBios services, including installation of these protocols if needed...", contained the clear qualification "if needed".
The statement is ancillary to the "fix" - and is essentially an addendum, which, in a proper case, may prove useful to some, especially to those who, for whatever reason, may decide or need to have these additional protocols installed and functional.
In addition, the presence of a given protocol on the client which is not present on the server may result in a warning message, one that presents the option to continue to establish the connection using the protocol that *is* available on the server or to "hang up".
Should this event occur, it could become a later and further point of confusion and misery and the solution to its avoidance or cure is to have the protocol, if needed, operational on the server or, alternatively, to eliminate it from the client when seeking to connect.
The original message sought to anticipate this event.
With Best Wishes.
