6.1a dos on a w2k client

[Bernard Lis]

Just replaced a W98 machine with a w2k. Every other time it connects it corrupts the server6.rbg file. "Server network access control file is damaged" I copy the backup server6 file onto the real one, then exit, then click the icon to get back in and all is ok.  If I exit and then click the icon to come back in, I get the above message. Then I do the copy, exit, back in and all is well.  I can repeat this procedure many times. Any ideas why this is happening?   Bernie Lis Megabytes, Inc.
