• Domain Trust 2008 to 2003

  - by nick3216

  I'm having trouble setting up the trust relationship between a Windows Server 2003 and a Windows Server 2008 AD. Domain a is Windows Server 2003 Forest functional level. Domain b is a Windows Server 2008 Forest functional level. I can set up the incoming side of the trust relationship on domain "a" so that it trusts domain "b". Try as I might on domain "b" I can't set up the outgoing side of the trust relationship to domain "a". The GUI interface gives an unhelpful 'The request is not supported'. I'm not sure netdom is being more or less helpful as it refers me to FilterSIDs netdom trust /add b /uo:b\admin /po:* /d:a /ud:a\admin /pd:* /oneside:trusting To improve the security of this external trust, security identifier (SID) filtering is enabled, however, if users have been migrated to the trusted domain and their SID histories have been preserved, you may choose to turn off this feature. For more information about SID filtering and how to turn it off, see the help for netdom trust /FilterSids or see Help and Support. The request is not supported. The command failed to complete succesfully. I say 'less helpful' because Windows Server 2008 doesn't support the /FilterSIDs option. How can we force creation of this trust? Edit: Just to clarify I've checked that the [Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options] "Network access: Allow anonymous SID/Name translation” is enabled on both sides of the trust as per http://social.technet.microsoft.com/Forums/en/winserverDS/thread/cc61fc25-3569-4413-bbfd-92390eb31118

• Logon Failure: the target account name is incorrect after making a ghost image of a server

  - by cop1152

  I recently replaced a failing SCSI drive in a Windows 2000 server with an IDE drive. I made an image of the SCSI drive and Ghosted it. The purpose of the machine was to give out DHCP at one location and host a couple of files. When I restarted the machine with the new drive, DHCP appears to be working fine, but I cannot get to any of the shares. Instead, I get the following message when attempting to navigate using Explorer. Logon Failure: the target account name is incorrect It appears that this machine is not communicating with the main domain controller. Changes to user accounts (performed on the domain controller) are not replicated on this machine.

• pam auth via winbind, howto map primary group for users?

  - by dr gonzo

  I have unix users authenticating to an PDC (via winbind) and want to have the primary group of those users a local unix group (e.g. www-data). users have the group "domain users" with gid 10006 (as the gid winbind mapping) idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum groups = yes winbind enum users = yes winbind use default domain = yes winbind nested groups = yes but want that the primary group is 33 for all users (www-data) how to achieve that?

• Multiple Domains on an Exchange Server

  - by William

  When I create a new user in exchange, it asks me to provide the User Logon Name. There is a dropdown box that supposedly allows you to select a domain for the user's login. What is this referring to? How can I make it so that I can create users with different domains in their user logon name? p.s. I am very aware of 'Accepted Domains' in Exchange allowing one user to have several email addresses in different domains. I am just curious how I can modify the user's Logon name specifically.

• Regression testing for firewall changes

  - by James C

  We have a number of firewalls in place around our organisation and in some cases packets can pass through four levels of firewall limiting the flow TCP traffic. A concept that I'm used to from software testing is regression testing, allowing you to run a test suite against a changed application to verify that the new changes haven't affected any old features. Does anyone have any experience or an offer any solutions to being able to perform the same type of thing with firewall changes and network testing? The problem becomes a lot more complicated because you'd ideally want to be originating (and testing receipt) of packets across many machines.

• Which Version Control Systems support LDAP/AD users and groups

  - by Jason Irwin

  Does anyone know which of the big players (if any) support LDAP/AD users and groups for authentication AND database permissions? Specifically, I'm wondering if SVN, GIT, Mercurial etc. will allow users to login/connect based on AD permissions and also allow granular permissions to be applied to folders within the VC database based on groups within AD. So far my research has not shown this to be possible....

• Windows VPN for remote site connection drawbacks

  - by Damo

  I'm looking for some thoughts on a particular way of setting up a estate of machines. We have a requirement to install machines into unmanned, remote locations. These machines will auto login and perform tasks controlled from a central server. In order to manage patching, AV, updates etc I want these machines to be joined to a dedicated domain for this estate. Some of the locations will only have 3G connectivity (via other hardware), others will be located on customer premises in internal networks. The central server (of ours) and the Domain Controller will be on a public WAN. I see two ways of facilitating this. Install a router at each location and have a site to site VPN between the remove device and the data centre where the servers are location Have the remote machine dial up and authenticate via a Windows VPN connection to the DC via RAS Option one is more costly to setup and has a higher operational cost. It also offers better diagnostics if the remote PC goes down. Option two works well but is solely dependent on the VPN connection been made before any communication can be made to the remote machine. In a simple test, I can got a Windows 7 machine to dial a VPN prior to authentication to a domain, then automatically login to the machine using domain credentials. If the VPN connection drops, it redials. I can also create a timed task to auto connect every hour in case of other issues. I'd like to know, why (if at all) is operating a remote network of devices which are located in various out of band locations in this way a bad idea? Consider 300-400 remote machines all at different sites. I'd rather have 400 VPN connections to a 2008 server than 400 routers, however I'd like to know other opinions on this.

• Squid on Linux Windows Pass through authentication

  - by beakersoft

  We are setting up a new proxy based on squid on an ubuntu server, and would like to have pass through authentication work for the Windows/Internet Explorer client. We have put the line into the squid.conf for squid_ldap_auth, but this prompts for a username and password in internet explorer. It does work ok once the user puts it in. Whats the 'best' (standard) way of using pass through authentication? Cheers Luke

• LAMP: How do I set up http://myservername.com/~user access?

  - by Travesty3

  Been trying to Google this, but I can't figure out good search terms to find any info about what I need, since I don't really know what it's called. I'm pretty much being thrown to the wolves to figure out how to set up a LAMP server. We had someone who knew how to do it, he set one up and then quit. It was set up so that when I went to "http://{myservername}.com/~travis" it showed the contents of my /home/travis/public_html folder. This worked fine, then we lost power and the server restarted (I know, battery backup, but this is a dev server in a dev building so it's OK). Now, the browser can't find that URL. I also need to know how to set this up on a new server, so instead of wasting time diagnosing this problem (probably just something dumb I did messing with settings or something), I really need to know how to set this up from scratch. Thanks for taking the time to read this and (hopefully) answer!

• Group Policy fault - Students force

  - by Richard 'Bean' Williams

  Work at a school and we've got a scenario. We block F8 on all computers so students cannot access Safe Mode to bypass Group Policy... But students are logging into their accounts using AD, and they are turning them off half way through. Then they are claiming that when they login next time, they have Local Administrator accounts. Is this right, but we have blocked F8 and Startup repair, so wondering how they actually did it. Cheers Richard

• Firewall GPO not applying despite being enumerated by gpresult

  - by jshin47

  I have a need to open up the admin$ share on all of my domain's client PC's and I am trying to do so using group policy. I defined computer policy for Windows Firewall with Advanced Security in a policy object linked to the appropriate container and added the appropriate rules. However, they are not being applied! I feel like I have tried all of the obvious steps: I've checked gpresult and the resulting set of policy is the way that I would expect it to look. I've gpupdate /force and gpupdate /sync on a few client computers, but no matter what I do they don't seem to respond to my changes. I know that other computer policies in the GPO are being applied so it is strange that these are not. I have also disabled exceptions on clients in the firewall GPO, but that doesn't seem to be applying either. Here is a screenshot of the firewall.cpl from a client: Basically, although other options in the same GPO ARE applied for computer policy, the firewall settings seem to be ignored.

• Using Folder Redirection GPO and Offline Files and Folders

  - by user132844

  I want to use Folder Redirection to redirect user's My Documents to a network share. First question is: What is best practices for mapping the drive? Should I use the profile tab in AD with the %username% variable, or a net use logon script, or something else? Second question is: How do I deal with laptops and syncing the network with the local storage? I want to have 2-way syncing so if they manually map their networked home drive and edit it from a different computer, it will sync the newer version to their My Documents folder the next time they connect their normal work computer. I also want to be sure that if they edit a file offline on their laptop while away from the office, that the network version syncs the changes the next time they connect that laptop. Please advise best practices for this scenario in a 2008 R2/Win7 environment. I am also interested in Mac clients for this environment, and while I am very Mac savvy, I would like to hear what others consider to be best practices for Mac network homedirs in a Win environment.

• Regarding AD Domain controllers and remote branch offices

  - by Alex

  We have central HQ building and a lot of small branch offices connecting via VPN and want to implement AD (If you can believe we still haven't). We want everyone to log in using domain accounts and be policed centrally. We are OK with having a RODC in a branch office with like 10 computers. But we have these small branches with two to four PCs only. Some of these branches connect to HQ via IPSec site-to-site VPN, some via remote access (client-based) VPN. So there is no problem with ones that have local RODC or connecting to HQ DCs via VPN router. But how about small branches? We don't really want to set up a machine there, neither we want to invest into Windows Server licenses or fancy network equipment. Also, the problem is that we cannot access HQ DCs via VPN because we are not logged in and connected to HQ internal network yet, so DCs aren't reachable. What is typically done in that situation if it is needed to have central management over policies on those PCs? Or is it better to let 'em loose and use local policies and accounts in this situation?

• Cannot authenticate a domain user with SQL Server 2008

  - by Sambo

  I'm new to setting up Domains so I might be missing something simple here... I've installed SQL Server 2008 on a Windows Server 2008 R2 box and I have another WS2008 R2 box acting as the domain controller. I've joined the SQL server to the domain and it seems to be behaving itself fine. I can ping the DC by name and IP address. I created a domain user 'SPSQLAdmin' that I want to use for database access with SharePoint but I can't seem to log on to SQL with this user. SQL complains, saying that the user belongs to an untrusted domain. I've configured the DC to delegate control for any service to the SQL Server but it doesn't improve the situation. What should I try next? Thanks in advance.

• Effective Permissions displays incorrect information

  - by Konrads

  I have a security mystery :) Effective permissions tab shows that a few sampled users (IT ops) have any and all rights (all boxes are ticked). The permissions show that Local Administrators group has full access and some business users have too of which the sampled users are not members of. Local Administrators group has some AD IT Ops related groups of which the sampled users, again, appear not be members. The sampled users are not members of Domain Administrators either. I've tried tracing backwards (from permissions to user) and forwards (user to permission) and could not find anything. At this point, there are three options: I've missed something and they are members of some groups. There's another way of getting full permissions. Effective Permissions are horribly wrong. Is there a way to retrieve the decision logic of Effective Permissions? Any hints, tips, ideas? UPDATE: The winning answer is number 3 - Effective Permissions are horribly wrong. When comparing outputs as ran from the server logged on as admin and when running it as a regular user from remote computer show different results: All boxes (FULL) access and on server - None. Actually testing the access, of course, denies access.

• Certificate enrollment request chain not trusted

  - by makerofthings7

  I am working on a MSFT lab for Direct Access, and need to create a Web certificate. The instructions ask be to do the following: On EDGE1, click Start, type mmc, and then press ENTER. Click Yes at the User Account Control prompt. Click File, and then click Add/Remove Snap-ins. Click Certificates, click Add, click Computer account, click Next, select Local computer, click Finish, and then click OK. In the console tree of the Certificates snap-in, open Certificates (Local Computer)\Personal\Certificates. Right-click Certificates, point to All Tasks, and then click Request New Certificate. Click Next twice. On the Request Certificates page, click Web Server, and then click More information is required to enroll for this certificate. On the Subject tab of the Certificate Properties dialog box, in Subject name, for Type, select Common Name. In Value, type edge1.contoso.com, and then click Add. Click OK, click Enroll, and then click Finish. In the details pane of the Certificates snap-in, verify that a new certificate with the name edge1.contoso.com was enrolled with Intended Purposes of Server Authentication. Right-click the certificate, and then click Properties. In Friendly Name, type IP-HTTPS Certificate, and then click OK. Close the console window. If you are prompted to save settings, click No. In production, our company has overridden the Web Server template and it doesn't seem to be issuing certificates with the full CA chain. When I look at the issued certificate properties then both tiers of the 2 tier CA hierarchy are missing. How can I fix this? I'm not sure where to look outside the GUI.

• Allow Windows Domain users Local Admin rights on subset of Domain Computers

  - by growse

  I'm a bit new to AD management, so would appreciate some help in what may be a very simple task. I've got a domain that manages a bunch of different servers, and I want to grant local administrative rights to some domain users to some of the servers (the development webservers). I appreciate the group concept, so I imagine I would have to create a group containing the users in question another group containing the computers to grant them access to. What's the best way of going about this?

• Putting a Windows DC, Exchange in a DMZ

  - by blsub6

  I have one guy at my company telling me that I should put FF:TMG in between my main Internet-facing firewall (Cisco 5510) and put my Exchange server and DC on the internal network. I have another guy telling me that I should put the Exchange server and DC in a DMZ I don't particularly like the idea of having my mailboxes and DC's usernames/passwords in a DMZ and I think that Windows authentication would require me opening up so many ports between my DMZ and my internal network that it would be a moot point to have it out there anyways. What are some thoughts? How do you have it set up?

• Is there an equivalent of SU for Windows

  - by CodeSlave

  Is there a way (when logged in as an administrator, or as a member of the administrators group) to masquerade as a non-privileged user? Especially in an AD environment. e.g., in the Unix world I could do the following (as root): # whoami root # su johnsmith johnsmith> whoami johnsmith johnsmith> exit # exit I need to test/configure something on a user's account, and I don't want to have to know their password or have to reset it. Edit: runas won't cut it. Ideally, my whole desktop would become the user's, etc. and not just in a cmd window.

• How do you get around security warnings when redirecting AppData?

  - by Oliver Salzburg

  I've recently set up folder redirection for my user profile in a domain. For now, I've redirected AppData, Desktop, Pictures, Documents and Favorites. So far, so good. But now I've noticed a quite disturbing side effect of the whole thing. Whenever I click any of my pinned elements on the task bar, I get the following warning: The shortcuts get synced as well and are no longer trusted. They're located at \\DFS\UserData\Profiles\OliverSalzburg\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar That seems like it could be a problem when rolling it out to the whole company.

• Joining new DC to AD - DNS name does not exist

  - by Andrew Connell

  I had a DC fail on me recently and trying to add a new one to my domain, although I'm sensing I might have other issues in my domain. I'm a dev at heart and know just enough about AD to be dangerous so looking for some assistance. My working DC is RIVERCITY-DC12. I'm trying to promote RIVERCITY-DC14 as a DC to the RIVERCITY domain, but when I run DCPROMO, at the NETWORK CREDENTIALS step where I point to the name of the domain (rivercity.local), I get "An AD DC for the domain rivercity.local cannot be contacted" and in the details see "The error was DNS name does not exist" Looking at RIVERCITY-DC12, I can see DNS is working, I've been able to query it from other machines in my domain, and no errors are reported in the DNS category within the Event Viewer. When I checked the FMSO roles, it shows RIVERCITY-DC12 is the machine for all listed roles. Not sure what I should do next or how to troubleshoot/investigate after searching around for a solution... ideas? Environment: Domain: rivercity (rivercity.local) Forest functional level: Windows 2000 (I'm more than happy to raise this) Windows Server 2008 All servers are Windows Server 2008 R2 SP1 (fully patched)

• TLS_REQCERT and PHP with LDAPS

  - by John

  Problem: Secure LDAP queries via command-line and PHP to an AD domain controller with a self-signed certificate. Background: I am working on a project where I need to enable LDAP look-ups from a PHP web application to a MS AD domain controller that is using a self-signed certificate. This self-signed certificate is also using a domain name that is not a FQDN - think of something like people.campus as the domain name. The web application would take the user's credentials and pass them on to the AD domain controller to verify if the credntials are a match or not. This seems simple, but I am having problems trying to get PHP and the self-signed certificate to work. Some people have suggested that I changed the TLS_REQCERT variable from "request" to "never" within the OpenLDAP configuration. I am concerned that this might have larger implications such as a man-in-the-middle attack and I am not comfortable changing this setting to never. I have also read some places online where one can take a certificate and place it as a trusted source within the openldap configuration file. I am curious if that is something that I could do for the situation that I have? Can I, from the command line, obtain the self-signed certificate that the AD domain controller is using, save it to a file, and then have openldap use that file for the trust that it needs so that I do not need to adjust the variable from request to never? I do not have access to the AD domain controller and as a result cannot export the certificate. If there is a way to obtain the certificate from the command line, what commands do I need to use? Is there an alternate method of handling this issue that would be better in the long run? I have some CentOS servers and some Ubuntu servers that I am working with to try and get this going on. Thanks in advance for your help and ideas.

• Give access to specific services on Windows 7 Professional machines?

  - by Chad Cook

  We have some machines running Windows 7 Professional at our office. The typical user needs to have access to stop and start a service for a local program they run. These machines have a local web server and database installed and we need to restrict access to certain folders and services related to the web server and database for these users. The setup I have tried so far is to add the typical user as a Power User. I have been able to successfully restrict them from accessing certain folders (as far as I can tell) but now they do not have access to the service needed for starting and stopping the local program. My thought was to give them access to the specific service but I have not had any luck yet. In searching the web for solutions the only results I have found relate to Windows Server 2000 and 2003 and involve creating security templates and databases through the Microsoft Management Console. I am hesitant to try an approach like this as these articles are typically older and I worry this method is outdated. Is there a better way to accomplish the end goal of giving the user permission to run the service and restrict their access to certain folders? If any clarification is needed on the setup or what we are trying to achieve, please let me know. Thanks in advance.

• How do I set up a one way trust when some DCs are firewalled off from each other?

  - by makerofthings7

  I have two Windows 2008 forests in Win2003 mode and I need to set up a one way trust between them. The validation button in Domains And Trusts works in one forest but not in the other. I think this is because not all DCs can see all the other DCs. I'm not sure if I need to set up the hosts file, so I did so with company.com in the respective domain along with the relevant DC. (do I need _msdcs _tcp zones etc) How do I set up a one way trust when some DCs are firewalled off from each other?

• What's the meaning of logging in as "[email protected]:something"

  - by Harvey Kwok

  My Windows 2008 R2 machine is joined to a domain. In the logon screen, if I type in "[email protected]:something" as the username, I can still logon properly, what's the meaning of ":something" appended at the end? I can even see the current user is displayed as "[email protected]:something" in the switch user screen. Is it a feature in Windows? Or is it just a bug? If it is a feature, what's the difference between logging in as "[email protected]" and logging in as "[email protected]:something"? Note that I tried different combinations like "mydomain\username:something" and "mydomain.com:something\username". None of them work except "[email protected]:something".
