Client access to Internet Service Manager

This question has three components.

1)I cant seem to gain anonymous access to my web server... or my ftp site from a client machine. If I login with a userid ... no worries.

Any suggestions ??

2)Each time I try to bring up my internal homepage on a client machine... it asks me for a userid/password combination.

These 2 items are probably linked in some way ??

I have set the Service manager to allow anonymous access to the www site and the ftp site.

One thing that I may have done is got the userid/password combination in the SAM out of sync with the Internet Service Mansger....

The userid in the SAM is IUSER_BDC .... and I possibly have to resync the psswords ???

If so ... how so ???

I was thinking that the passwords became de-synced because I rebuilt the BDC and then reinstalled the Internet Information Server without firstly deleting the IUSER_BDC from the SAM database ???

3)I dont know if this is related.... but on the BDC i receive an event in the event viewer that says 'Remote access Security Failure. A network error has occured while trying to establish a session with the security agent on LANA2. The error is in the data.

The data contains 0000: 23 00 00 00.

On BDC, when I check the connection for LANA2 in my NetBIOS  Configuration popup I see this ...

LANA2    NetBT -> RTL8029 -> RTL80291

I understand that RTL8029 is my network card ... but what is RTL80291 ??? possibly the network card on the  PDC ?? but the same network card is installed on the PDC as well (another SN3200... which uses the Realtech Chipset)

When I check my Event Viewer on the PDC,there is no error reported.

Any help in these areas of configuration would be appreciated.

Thanks in advance
