I am stumbling over the Windows XP Pro simple file sharing and any one that can assist me in helping with this problem I would be so appreciative! I have an application that was written for one of my clients that I am configuring a machine for it to run on. In the past the developer only got it to run on W2k because of the way that 2k does local authentication. With XP it requires the guest account authentication for network access to that machine. This is the way it works...the application is installed on client pcs and the "server" pc (it is a win xp pro box) has MSDE 2000 sp 3 installed and running. The app connects to the sql backend using windows authentication. Here is where my problem begins with XP although it shows the user account authenticating it still forces the guest account to authenticate to the networked resources .i.e. the SQL backend. This is causing an error return from SQL with a null user account. I have changed my local security policy to disable the forceguest account and set it to the classic - local users authenticate as themselves. I thought that maybe this setting would solve my problem but it hasn't if anyone else has any insight into my problem or if you need further explaination... I am setting points to 500 because I have been working on this for awhile now and it is more "I have come from you will never get this to work to getting it to work with a work around" now I just want to get it to "work".
