xp pro, granting domain user access to local resources?
Hi All: I have an SBS2003 domain with a number of xppro sp2 clients. All the
computers are members of the domain, and I've set up domain users for each computer. I have a USB scanner installed on one computer, and when a user logs on to the local machine, they can access the scanner, but if they log on using the domain account, they get an error when the scanner application tries to load the (presumably) USB drivers for the scanner. It seems like a local security policy issue, but I can't figure out what privileges the domain user needs to have the same access the local account has? -- |

If the scanner is installed already, this is unlikely to be a driver issue. More likely, the software you're using is expecting the user to have administrative rights on the workstation in order to run the app. First, I'd contact the software developer and ask for a workaround which does *not* involve granting domain users admin rights - this is sloppy code, and they need to fix it. If you get nowhere with them, try downloading Process Monitor from Microsoft (a cool Sysinternals tool) that will help you find out what areas of the file system & registry the app expects to write to, so you can manually edit/correct it. |

Thanks for the quick reply. This is an older Plustek scanner and I don't
expect the manufacturer will provide any updates for it. And yes, the default user account locally has Admin rights, so you probably nailed it. I don't have any issues granting the domain user admin rights on the workstation, unless it opens up other vulnerabilities beyond them breaking something g. Short of that, what would I need to manually edit to grant access? do you mean granting the domain user appropriate access to specific folders they'd normally not have access to?

And yes, the default user account locally has Admin rights, so you probably nailed it. You can test this by adding the domain user to the local Administrators group.... I don't have any issues granting the domain user admin rights on the workstation, unless it opens up other vulnerabilities beyond them breaking something g. Ain't that enough for you? Malware infestation can take a long long time to clean up, as well as cause problems on the network. :-) Short of that, what would I need to manually edit to grant access? do you mean granting the domain user appropriate access to specific folders they'd normally not have access to? Yep - and registry keys. Do check out the Sysinternals tool. It's a good thing to know how to use. Log in as the non-admin user, then launch the Sysinternals tool using RunAs & providing valid local admin credentials. Play with it a bit. Thanks again!

You may experience some problems if the software was designed for Win9x/Me, or if it was intended for WinNT/2K/XP, but was improperly designed. Quite simply, the application doesn't "know" how to handle individual user profiles with differing security permissions levels, or the application is designed to make to make changes to "off-limits" sections of the Windows registry or protected Windows system folders. For example, saved data are often stored in a sub-folder under the application's folder within C:\Program Files - a place where no inexperienced or limited user should ever have write permissions. It may even be that the software requires "write" access to parts of the registry or protected systems folders/files that are not normally accessible to regular users. (This *won't* occur if the application is properly written.) If this does prove to be the case, however, you're often left with three options: Either grant the necessary users appropriate higher access privileges (either as Power Users or local administrators), explicitly grant normal users elevated privileges to the affected folders and/or part(s) or the registry, or replace the application with one that was properly designed specifically for WinNT/2K/XP. Some Programs Do Not Work If You Log On from Limited Account http://support.microsoft.com/default...;EN-US;q307091 Additionally, here are a couple of tips suggested, in a reply to a different post, by MS-MVP Kent W. England: "If your game or application works with admin accounts, but not with limited accounts, you can fix it to allow limited users to access the program files folder with "change" capability rather than "read" which is the default. C:\cacls "Program Files\appfolder" /e /t /p users:c where "appfolder" is the folder where the application is installed. If you wish to undo these changes, then run C:\cacls "Program Files\appfolder" /e /t /p users:r If you still have a problem with running the program or saving settings on limited accounts, you may need to change permissions on the registry keys. Run regedit.exe and go to HKLM\Software\vendor\app, where "vendor\app" is the key that the software vendor used for your specific program. Change the permissions on this key to allow Users full control." -- Bruce Chambers Help us help you: http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/default.aspx/kb/555375 They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. ~Benjamin Franklin Many people would rather die than think; in fact, most do. ~Bertrand Russell The philosopher has never killed any priests, whereas the priest has killed a great many philosophers. ~ Denis Diderot |
