Deaktiver: "Advarsel denne fil er muligvis ikke sikker"

Jeg har været ude for det samme - dødirriterende. For mig opstod det, når jeg åbnede filerne fra netværksdrev - kopierede jeg filerne over på desktoppen, så var det ok.

Du skal ind og rode i sikkerheds-opsætningen i Officepakken og IE - det er det eneste jeg kan sige.  Men har du prøvet at søge på fejlmeddelselsen på MSDN ?

Nej har ikke lige kigget på MSDN, men tvivler på at jeg finder så meget med en dansk fejlmedd.

Engelsk tekst (fandt den via Google) - der matcher det problem jeg havde.

Microsoft Access cannot open this file.
This file is located outside your intranet or on an untrusted site. Microsoft Access will not open the file due to potential security problems.
To open the file, copy it to your computer or an accessible network location.

....
This behavior can occur because an FQDN or IP address contains periods, which causes Internet Explorer to identify the Web site or share as being in the Internet zone.
....

To work around this behavior, each user must add *.domain.com or the appropriate IP address range to the Local Intranet Sites dialog box:
1.    In Internet Explorer, click Tools, and then click Internet Options.
2.    On the Security tab, click Local intranet and then click Sites.
3.    Click Advanced, and then type: *.domain.com or an IP address range (for example, 157.54.100-200.*) in the Add this Web site to the zone box (where domain.com is your company and top-level domain names).
4.    Click Add, click OK, click OK, and then click OK to close the Internet Options dialog box.

heh; Microsofts hjemmeside

In Access 2003, a Security Warning dialog box may be displayed when you try to open an Access 2003 database if either of the following two conditions is true:
1. The security level is set to Medium, and your Access 2003 database does not have a digital signature.
2. The security level is set to High, and your Access 2003 database has a digital signature. However, the digital signature is not in the trusted publishers list.

...

Løsning er så, at gå ind i Tools, Macro og sætte security til Low - hvad der generelt ikke kan anbefales...  Jeg ville nok forsøge at få tippet ovenfor til at virke - men videre om at ændre sikkerhedsniveauet:

The user (or IT administrator) selects from one of three security levels that control how Access behaves when starting databases. This security level is common for all signable objects, including COM Add-ins, the database VBA project, and macros the user has. COM Add-ins and Add-in Manager type add-ins will respect the “Trust all installed add-ins and templates” checkbox on all security levels. If security levels are low, Access will behave as in previous releases. If security levels are high, Access will only open databases that have a trusted digital signature.

Tror bare jeg lader den stå på high så
