Security permissions

Posted on 2006-06-24

Hi-
I am running XP Pro on one laptop and XP Home on another.
I have a USB external drive that I have connected to my XP Pro laptop.  I have set the Security permissions so that only my user ID and SYSTEM have access to partitions on the USB drive.

My XP Pro laptop is going in for repairs - and I want to be able to access the USB drive from my XP Home laptop.  However, I get "Access is denied".  Both laptops have the same account name and password (workgroup environment), although in permissions, the Computer Name precedes my account name.

While connected to my XP Pro laptop, I changed the permissions to one of the partitions on my USB drive to "everyone" which allowed me to access this partition when connected to my XP Home laptop.
I then booted my XP Home laptop into Safe Mode and logged in as Administrator and changed another partition's security permissions on the USB drive to my account name with full access.  HOWEVER, even though the Advanced Security Settings show "This folder, subfolders and files", I am unable to access folders in the partition and receive "access is denied".  When I click on the security tab for a folder, I get "You do not have permissions to view or edit the current permission settings for <foldername>, but you can take ownership or change auditing settings."  I do not wish to take ownership and am wondering why this is happening??

Questions:
1) Can I change the security permissions for multiple partitions at the same time (instead of one at a time)?
2) Is there a way to change the security permissions without having to reboot into safe mode on an XP Home machine? (e.g. BartPE?  Recovery Console?)
3) Is there a way to set security permissions from the XP Pro laptop to allow my XP Home laptop to access the USB partitions?  i.e. I think I need to be able to add "XP Home computer name\account name" while the USB drive is connected to the XP Pro machine.  Since I am on a workgroup, is there a way to do this (i.e. it should be able to find the XP Home machine on the network and recognize that "XP Home computer name\account name"  is a valid object??
4) Why am I getting "access denied" for folders in partitions after I have set the security permissions for the partition and subforlders/files??

Thanks-

In most cases there is no problem. The drive shows up as a secondary drive and I browse to the folder and can copy the files.

When you see this error you must turn off simple file sharing, which is enabled by default in Windows XP Pro and then take ownership of the folders.

To turn off simple file sharing open up Windows Explorer and select Tools and then Folder Options and click on the View tab. In the Advanced Settings window locate Use simple file sharing and uncheck it. Click OK and it will be disabled.

To take ownership of the folders, locate the ones you want and right click them and select Properties. Here you will see a Security tab. Click this tab and if a security message appears just click OK. Click on Advanced and then go to the Owner tab. Locate your user name in the Name list or select the account you are logged in with and check the box that says "Replace owner on subcontainers and objects."

* If you are running Microsoft Windows XP Home Edition, you must start the computer in safe mode, and then log on with an account that has Administrative rights to have access to the Security tab.

Click OK. If you get a box popping up that says "You do not have permission to read the contents of directory folder name. Do you want to replace the directory permissions with permissions granting you Full Control? " Click Yes.

Click OK and then give yourself full permissions on the folders using the check-boxes.

That's it. You can now access your files.

Hi Merete
>> if the external drive is a slaved drive then it shoudl just appear in my computer as d drive?
The drives do appear, but I am unable to get access to them because of permissions.  See details I provided.

>> you must turn off simple file sharing, which is enabled by default in Windows XP Pro
I am using XP Home when experiencing the problem...


Again, my Questions are:
1) Can I change the security permissions for multiple partitions at the same time (instead of one at a time)?
2) Is there a way to change the security permissions without having to reboot into safe mode on an XP Home machine? (e.g. BartPE?  Recovery Console?)
3) Is there a way to set security permissions from the XP Pro laptop to allow my XP Home laptop to access the USB partitions?  i.e. I think I need to be able to add "XP Home computer name\account name" while the USB drive is connected to the XP Pro machine.  Since I am on a workgroup, is there a way to do this (i.e. it should be able to find the XP Home machine on the network and recognize that "XP Home computer name\account name"  is a valid object??
4) Why am I getting "access denied" for folders in partitions after I have set the security permissions for the partition and subforlders/files??

Better hurry up then :D or you'll have your other computer back by then.
Have you looked in Disk Management?  Maybe you need to just allocate the "missing" partition with a drive letter for it to be available.
have you checked the pin on the rear is set to slave?
Take ownership of the drive here's how

3) Is there a way to set security permissions from the XP Pro laptop to allow my XP Home laptop to access the USB partitions?
 If you can access them in xp pro  then simply share them, rightlick the slaved drive name and share it. Fully. Your xp home should  detect it after a little wait within the my network neighbourhood.
I dont use all this log on and security stuff rather just use programs and be careful. I dont get any viruses or malware with good monitors inplace.
Do you have a firewall running?

>>Better hurry up then :D or you'll have your other computer back by then.
Yup - expecting it back tomorrow - but now that I have 2 laptops, I plan to share the USB drives going forward and still need to resolve the problem.

>>the "missing" partition
There is no missing partitions!  As I have said, the drives appear but I am unable to get access to the folders.

>>have you checked the pin on the rear is set to slave?
not relevant - see a few lines up re: missing partition

>>Take ownership of the drive
Don't want to - I only want to ACCESS it and not do anything to affect me being able to also access it from the other laptop

>>If you can access them in xp pro  then simply share them, rightlick the slaved drive name and share it.
This is relevant to accessing over a network; the scope of my questions have to do with the USB drives being accessible by the laptop to which it is connected

>>Do you have a firewall running?
yes

SAbboushi  do you have this question posetd somewhere else?

this is confusing, all my suggestions were for you to access the USB drive while the xp pro is in the shop, but now you say its not relevent??? ok now you have your xp pro laptop back.
What are you referring to a missing partition, I havent  seen any mention of a missing partition?? Please xplain.
ok recapping..
You say>
 (1) While connected to my XP Pro laptop, I changed the permissions to one of the partitions on my USB drive to "everyone" which allowed me to access this partition when connected to my XP Home laptop.<< so you unplug the usb drive and reconnect it to the xp home laptop??<< you fill in the gaps here ok.

(2)I then booted my XP Home laptop into Safe Mode and logged in as Administrator and changed
 ""another partition's ""
security permissions on the USB drive to my account name with full access. << aheh I think this is the problem, maybe you should have performed any changes to all partitions as in changed all or any permissions on one Laptop the xp pro only.

(3) on the xp home laptop in safemode or normal mode>>HOWEVER, even though the Advanced Security Settings show "This folder, subfolders and files", I am unable to access folders in the partition and receive "access is denied".<<what format is this ntfs or fat32?

(4)When I click on the security tab for a folder, I get "You do not have permissions to view or edit the current permission settings for <foldername>, but you can take ownership or change auditing settings."  I do not wish to take ownership and am wondering why this is happening??<< xp pro has to take onwership, you say you have created the accounts in the same name same pasword but xp pro rules first, if you take ownership in xp home it hopudl be ok in xp pro.


What you should do is put in the permissions to everyone for all your partitions on the xp pro first.
How many partitions are we talking about please give me some kind of overall scope of what you have there.
Then on the xp home you shoudl be able to access these drives fine as you have freed them for xp home to access.
What firewall do you have running.
Can you access shares on the xp home to xp pro laptop in the c docs and settings shared folder?
What do you see in the my network neighbourhood on both computers.
It maybe the firewall settings
I need to know what firewall ok, is it zone alarm? Shut down the firewall for a test wait a bit and see if your permissions problem stops.

Hi Merete-

I really appreciate all the time and effort that you have put into trying to help me.  Sadly, your last link does not seem to fix my problem.

I decided to upgrade from XP Home to XP Pro on this other laptop and see if this helps resolve my problem.

Thanks again for your efforts-
Sam

No - I don't believe so.

>> this is confusing, all my suggestions were for you to access the USB drive while the xp pro is in the shop, but now you say its not relevent??? ok now you have your xp pro laptop back.
Sorry but I am unclear on what you are referring to.  What I said was not relevant was the pins re: slave/master on the external USB drive.


>>What are you referring to a missing partition, I havent  seen any mention of a missing partition?? Please xplain.
Your choice of words, not mine ; )
You said "Maybe you need to just allocate the "missing" partition with a drive letter ..."

>>so you unplug the usb drive and reconnect it to the xp home laptop??
YES

>>aheh I think this is the problem, maybe you should have performed any changes to all partitions as in changed all or any permissions on one Laptop the xp pro only.
SORRY - DIDN'T UNDERSTAND WHAT YOU ARE SAYING HERE.  ARE YOU REFERRING TO MY QUESTION ABOUT BEING ABLE TO DO MULTIPLE PARTITIONS AT A TIME INSTEAD OF ONE AT A TIME.

>>what format is this ntfs or fat32?
NTFS - I DO NOT BELIEVE YOU CAN SET PERMISSIONS ON FAT32

>> xp pro has to take onwership, you say you have created the accounts in the same name same pasword but xp pro rules first, if you take ownership in xp home it hopudl be ok in xp pro.
THANKS FOR THE SUGGESTION BUT I AM NOT WILLING TO TAKE THE RISK


MY DECISION STILL STANDS - UPGRADE TO XP PRO.  YOUR EFFORTS AND SOME OF THE THOUGHTS IN THIS POST LOOK LIKE THEY MIGHT HELP RESOLVE THE PROBLEM, SO POINTS ARE YOURS.

With Regards-
Sam
