The member of the replica set you are attempting to use has been removed because either it has not been synchronized within the required number of days (retention period) or it has been synchronized with a second Design Master. The member should be deleted from your computer.
If there is data in the member that has not been synchronized with any other member in the replica set, manually enter that data in another member. You can determine which records have unsynchronized data by examining the s_Generation field in each table. A value of 0 in the s_Generation field indicates the record is an inserted or updated and has not been synchronized with another replica in the set. To view the s_Generation field, open Microsoft« Access, go to the Tools menu, click Options, select the View tab, and then select the System Objects check box.
If the member is the Design Master, compare the structure of the replica with another replica in the set to determine whether any design changes have not been synchronized.
