I have a database that the client needs to update. They like to use access. Some tables randomly become read-only for them. Any ideas why?

They are using Access 2007 and MS SQL 2005.

SQL Table:

CREATE TABLE [dbo].[Users](
    [SyncGroup] [varchar](20) NULL,
    [UserID] [varchar](20) NOT NULL,
    [Password] [varchar](20)  NOT NULL,
    [Restriction] [text] NULL DEFAULT (' '),
    [SiteCode] [varchar](20) NULL,
    [Group] [varchar](20)  NULL,
    [EmpId] [varchar](20)  NULL,
    [TimeZoneOffset] [int] NULL,
    [UseDaylightSavings] [bit] NULL,
    PRIMARY KEY ([UserID]) )

    Access really likes having a TimeStamp aka RowVersion field on every table. I don’t know if this will fix your problem though.

    “On servers that support them (such as Microsoft SQL Server), timestamp fields make updating records more efficient. Timestamp fields are maintained by the server and are updated every time the record is updated. If you have a timestamp field, Microsoft Access needs to check only the unique index and the timestamp field to see whether the record has changed since it was last retrieved from the server. Otherwise, Microsoft Access must check all the fields in the record. If you add a timestamp field to an attached table, re-attach the table in order to inform Microsoft Access of the new field.”
