Question

Cannot enable access sharing.

Asked by: yonixxx

I have XP with 2 lan card.

One is connected to my hub and the other to my dsl modem.
Work fine for several month.

After a crash i was unable to get connection to the internet from my other machine. I check Network Connections and find out "Internet Connection Sharing" was off. Trying to put it on i get : "Cannot enable access sharing Error 1068 : The dependency service or group failed to start".

Trying repairing the connection i got :"The following steps of the repair operation failde:
Renewing IP Address
Purging the DNS Resolver cache".

I had another lan card to check it goes the same.

I have tried every option in ipconfig to get rid of the DNS Cache " Could not flush the DNS Resolver Cache : Function failed during execution".

In my administrative/Services tool look for anything DNS... Found DNS Client (dnscache) it was stopped. Clicking start "Could not start the DNS client service on local computer, Error 5:Access is denied"

Remove the 2 lan card, reboot and reinstall step by step the usb connected one and after the dsl connected.
After all do a point of restore.

Hope to be helpful.

Ok, folks...

I didn't change a things on the original "problem" hard disk and needed to get back data from it.

I have found that i can't get some files because of :

Access denied.

It seams that during the process to restore my hard disk (fixboot and so on) something happen to the authorization of some files : May be also the cache or some controling DNS Resolver Cache.

As my computer culture come from Mac i don't know nothing about authrization on Windows.

I guess i should learn how to reset authorization or check them out (espacially those about lan and DNS process).

Any directions ?

Ok,

Logged as administrator i guess i can change all ownership.

BUT...

1/

What was the exact ownership of my system file (DNS Resolver cache or others) that are now changed ?

Is there a way to set the windows or system file back to their original ownership ?

2/

Where are such kind of file hidden ?

 

by: stevenlewisPosted on 2003-02-14 at 14:57:44ID: 7953440

What was the exact ownership of my system file (DNS Resolver cache or others) that are now changed
the system owns those files
I thought you were talking about files such as my documents and things like that
Windows does protect system files and such
in order to see all file, go into windows explorer, tools, folder options, view, and check show all files, and uncheck hide protected files and system files

When you setup the new OS, the ownership of the old files was you, but the new OS doesn't know this, that is why you have to take ownership of them (windows security)

 

by: yonixxxPosted on 2003-02-16 at 21:53:00ID: 7963912

"What was the exact ownership of my system file (DNS Resolver cache or others) that are now changed"

If i knew... lol

I guess "SYSTEM" or "Administrator" something like that.

I have set the "see all" option in folders options.

But after a quick check, i don't know were to look for that kind of files or caches (DNS Resolver cache or others).


The point is that i didn't (on this disk) set any new system.
BUT i have repaired it under safe mode "administrator" and under DOS console. I guess that's where the change of ownership occurs.

To be practical :

1/ What is the original owner of systemm file (if it is not fixed, were can i check who was it) ?

2/ Where can i find DNS Resolver cache (i didn't find a file by that name) ?

3/ I guess with that info i can correct the problem but, if i create a new file or system change it again will he again "write" it under a wrong owner ?


Frankly Steve, i have set another disk but i love to learn lol

 

by: stevenlewisPosted on 2003-02-17 at 09:39:46ID: 7967583

1/ What is the original owner of systemm file (if it is not fixed, were can i check who was it) ?
the system. the system has an account in nt based os's and this account owns the files

2/ Where can i find DNS Resolver cache (i didn't find a file by that name) ?
I will have to do some research on it, but I think it is kept in memory, not in an actual file

3/ I guess with that info i can correct the problem but, if i create a new file or system change it again will he again "write" it under a wrong owner ?

a new file is owned by who created it
If you create it, then you will own it
but (and here is the caveat) in NT ownership is not a based on a name, but an SID (Security IDentifier) every account gets a security identifier
so when you set up the new OS on the second disk, while your username was the same, the os saw a different sid that owned the other file, and that's why you had to take ownership
I hope this makes things as clear as mud LOL. It can get confusing
each file/folder has an ACL (access control list) and it checks the SID against what it has in the ACL to decide whether to allow access or not. You new sid was not on the list, but M$ included a feature for just this scenario (and in a network environment if the person who created the file (and the file may be needed for others) gets fired, and no one can access it, the administrator can take ownership of the file, and then assign the appropriate permissions)
So you , as the admin took ownership of your own file, which XP thought wasn't yours (due to the SID)

 

by: yonixxxPosted on 2003-02-19 at 01:05:58ID: 7980325

Ok, Steve of course it is clear (as always with MS lol)

Well,

I have understod most of your explanation.

But the DNS Resolver Cache is bothering part.

It is the second time it occurs to me and each time i had to restore old image or formet and re-install.


I don't think it is in memory.
As i restarded and restard and agin even in safe mode. It was still alive. Even if there is no file by that name, the info about it should be stocked somewhere.

This file ownership is the problem. We should find a way to get ride of it (system will create a new one with correct SID) or change it ownership.


BTW Steve, your infos are very instructing.

 

by: stevenlewisPosted on 2003-02-21 at 19:20:14ID: 7997117

still researching the dns cache files
but there is a command to flush the dns cache
from a prompt
ipconfig /flushdns

by: yonixxxPosted on 2003-02-24 at 23:48:26ID: 8014809

Thanks to Steven we can understand ALL about Caching and DNS on Windows.

Next time we'll try to find how to restore ORIGINAL OWNERSHIP to system files after a crash ! :)

 

by: stevenlewisPosted on 2003-02-25 at 15:49:11ID: 8021361

Glad to help
as to the original owner of system files, I doubt it, because evemn the system has an SID, and a parallel install uses a different SID, and since you can only take ownership, and then allow it to be taken by another, you can't get the system to take ownership. You can give it permission to take ownership, but of course it won't (this has to be a consious effort, done by humans :~)

 

by: stevenlewisPosted on 2003-02-25 at 15:49:41ID: 8021369

I mean you can't assign ownership of a file

 

by: SmartGuysPosted on 2003-04-21 at 10:35:15ID: 8367856

You don't have to that.
