Add and set a key in Remote Systems's registry in C#

P

Parv

I am working in a domain environment. I am on a client machine and
wants to edit registery of domain server. I am currently in a Domain
user account and member of Domain administrators on the domain
controller. I am able to open registry manully by connecting the remote
registry. While doing the same programatically i am getting the
following exception :

CODE :

RegistryKey baseKey =
RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, "server");

RegistryKey sk1 =
baseKey.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\EXIFS\Parameters");
string key = "incoming";
sk1.CreateSubKey(key);
sk1.SetValue(key, 1, RegistryValueKind.DWord);

EXCEPTION:

System.UnauthorizedAccessException was unhandled
Message="Cannot write to the registry key."
Source="mscorlib"

Are you sure the code runs as domain admin?
To make sure, turn on security auditing on the DC and watch the security
eventlog, this should contain a message specifying the account that failed
to access the registry object.

Please be more specific, what's your own system and what account are you
running under?

the Domain Controller. Now i want to update registry of my domain

Please be more specific, what's your own system and what account are you
running under?

Sorry if I wasn't clear, but you have to enable "registry object access"
auditing, that is from regedit select the key you want to audit and add the
user or group you want to monitor. Then, using "Local Security Policy"
editor, you must turn-on; Local Policies - Audit Policy - Audit Object
Access for Failure. When done, each unsuccessful access will be logged in
security log and will contain the account used to modify a key or subkey.
