• Group Policy for Setting Passwords: Server 2003 Domain

  - by user1236435

  In my 2003 domain, I am being requested to set a password policy to require passwords to expire every 4 months, and also require users to change their password on their next login, due to a security issue. In my domain, my OU's are setup by location, then drilled down to city, then the users and computers are in separate sub-domains. My question is, how do I set this up for my domain? Will I need to set the policy up for loop back? Can I configure this for just a specific OU? Any suggestions on how to move forward? Any advise is much appreciated, and thanks in advance!

• How does /burnmemory=XXX boot.ini switch work?

  - by user371602

  I know what the /burnmemory switch does on Windows, but I'd like to understand what Windows is doing under the hood to support it. It's described on msdn as the "amount of memory, in megabytes, that Windows cannot use". Does this mean simply that the kernel does not allow user virtual memory mapping into this area? How is this accomplished in the kernel, and are there other restrictions that the kernel will make when burnmemory is set?

• Sharing a serial port between two processes

  - by peterrus

  As it is not possible to directly share a serial port between two processes using Linux, I am looking for another way to achieve this, I have heard about socat but could not find a concrete example of how to realize the following: Split one physical serial port (/dev/ttyUSB0) into two virtual ports, one for reading and one for writing, as one process only needs to send data, and one only needs to receive data. I can no modify the sending application unfortunately.

• BIND9 DNS Records not Propagating

  - by natediggs

  Kind of new to managing DNS via BIND. We have a setup with a master server and a slave server. I've updated the zone file on the primary name server for our domain but the changes aren't propagating over to the secondary server. The funny thing is that I'm making a change in the zone file for a different domain on the server and those changes ARE being propagated to the secondary server. Anyway I can force the change to be made? Also, there was a third nameserver that used to be operational but has been offline for a few months now. I removed it from the zone file for the two domains that have it listed as a name server and it still (over 24 hours later) shows up from time to time when I run a record check. Any help on this would be greatly appreciated. Nate

• What TLDs should I use for my NS records for redundancy? (DNSSEC support required)

  - by makerofthings7

  Question As a general practice, is it a good idea to use multiple TLDs for the name servers? How should I choose between which TLD would be a good candidate for being the root server for my NS name? More Info I am switching over 800 DNS zones to an outsourced DNS provider. I originally planned on setting the zone names to nsX.company.com, but think it would be best to have multiple TLDs such as .net , .org and .info Since I plan on supporting DNSSec at company.com I think all the 1st tier Name servers must support it as well. Part of the inspiration for this question came from our provider UltraDNS. In their configuration screen for our domains, they actively verify and alert us if our name servers aren't exactly: pdns1.ultradns.net pdns2.ultradns.net pdns3.ultradns.org pdns4.ultradns.org pdns5.ultradna.info pdns6.ultradns.co.uk

• Chrome Residual Redirect to Login Page

  - by Shadow503

  My college redirects people in the dorms to a login page when using an ethernet (or wifi) connection. I am now at home, and certain domains keep redirecting to this login page. I've tried running ipconfig /flushdns and I flushed the chrome's local dns cache as described here: How to clear/flush the DNS cache in Google Chrome?. Interestingly enough, while http://www.reddit.com redirects to the login page, http://www.reddit.com/r/funny works. Firefox works fine for both urls. Is there a way to fix this without deleting all of my cookies? Thanks!

• Virtualization software for windows 7

  - by user23950

  I've been using Shadow User and Deep freeze for windows xp. But I don't think its compatible with windows 7. Do you know of any application that can achieve the same thing? Please don't tell me to use Returnil virtual system because I've had a really bad experience with it when I'm using xp. The system just restarted over and over. And I have just reformatted by that time.

• iSCSI NAS supporting VMware Esxi 5.1 servers in a software development environment

  - by BigTFromAZ

  I would like to build (or purchase) the smallest, quietest most energy efficient servers that I can for a low demand environment. These would only have a small disk for guest swap files, a CPU (XEON preferred), 32 Gb of memory and minimal graphics. The virtual machines need to be up but demand will be quite low. Any thought on case, format processors, fans, motherboard, et al? Small, quiet and lots of RAM are the operative words here.

• Which guide do you recommend on setting up Nginx

  - by Saif Bechan

  I am setting up an LEMP (Nginx, MySQL, PHP on Linux) from scratch. There are a lot of guides available online in all different forms.

• Impossible to Remove FTDI driver / FTDI Enumeration on Windows 7

  - by Joe

  I have already read the : Is it possible to reset FTDI virtual com ports enumeration, we easily get hundreds of COM ports in production environment topics which was pretty interesting ! But I got a problem, apparently I can't delete the ftdi driver, so I can't use the previous conclusion of the topic... I'm really stuck and bored of this problem, my com port number is 132 ! Does someone have another solution ?

• Forward e-mail to multiple addresses with conditions

  - by Valera Leontyev

  I need to forward e-mails to different mail accounts by different conditions. The aim is to create mail notification scheme for my company. I'd like to setup server on dedicated mail domain for it. Is there any software that helps to get my aim (Linux)? Examples: 1) forward all e-mail sent to [email protected] to x@x, y@y, z@z (no conditions) 2) forward e-mail sent to [email protected] where subject contains '[finance]' to a@b and b@b 3) forward e-mail sent to [email protected] where subject contains '[fault]' to s@s and s2@s. Receivers' domains are different. P.S. Now we use Gmail filters to get this functionality, but it's unstable and hard to maintain.

• Is it preferable to use POP or IMAP to check multiple google mail accounts from one?

  - by Adam Tuttle

  I have email accounts on several domains that use Google Mail, and thus far I've only ever used POP to send and receive mail from a single inbox. This is quite functional, and as long as I remember to select the appropriate FROM address when starting a new thread, mostly works without any additional thought: messages received on account A are replied to via account A, and so on. My only complaint is the lag -- I've seen sometimes as much as a half hour between messages arriving in an inbox before being imported into my primary inbox via POP. My question is this: Google also supports IMAP. Would that be in any way preferable over POP access? Reduced lag would be nice, but not at a general speed cost, if everything I do has to check another mailbox too.

• Tweaking "Most visited sites" button in Firefox

  - by Mehper C. Palavuzlar

  It is sometimes practical to use "Most Visited" sites which stands on the left hand side of Firefox window. When I click on it, I can see maximum 10 URLs. At that point, I have 2 questions: Is it possible to increase the number of maximum most visited sites (say, 30)? Let's say example.com is one of the most visited domains. In the most visited list, there are other pages from this domain, like example.com/intro, example.com/info, example.com/help etc. So those sub-addresses are also in the list, but I just want to see max 1 (or maybe 2) pages from the same domain in the list. Is it possible to arrange the list this way?

• My Domain Is Getting Blocked As Gambling

  - by Tim Scott

  I have a site at http://slotted.co. Some of my would-be users complain that their company firewall blocking access. At least one user told me it was flagged as a gambling domain, which it is not. What can I do about this? Incidentally I own some other domains, such as signupster.com, which redirect to my site. I wonder if a quick workaround would be to make that my main domain and have slotted.co redirect? Obviously I prefer in the long terms that slotted.co is considered clean.

• git-daemon fails on VM suspend and resume

  - by fuzzy lollipop

  I have Gitorious running on a Centos 5.3 install on a VMWare virtual machine under VMWare Server. Everytime we take down the server via suspend to back up the image, and resume the VM, the git-daemon dies. All my other processes continue to function without any problems, this one process dies and has to be manually be restarted. Does anyone have any ideas why this might be happening, or how to make sure this process never dies off?

• New Servers Active Directory and Exchange

  - by user3164638

  I have 3 Dell PowerEdge server, each with 2 quad-core processors. I am going to bring this office out of the stone-age network (P2P, share files on a flash drive, emails through Google, etc) and set up Active Directory and Exchange 2013. Our needs are not that great at the moment - our staff consists of approximately 40 people, and our network may eventually be managed by an external company. We need only one domain for our emails (though we may serve emails for a few other partners domains as well). I was thinking of setting something up like this: Server 1: Primary DC. Active Directory and Exchange on separate virtual machines. Server 2: Redundant of server 1. Server 3: Shared resources, storage, backups, etc. How would you utilize 3 servers for an Active Directory / Exchange setup for a small/medium office? We do have plans to grow, so my solution must be scalable, though I'm not sure that I want to split permissions, though I'd consider it if that was something that could be changed on down the road.

• Using prf file to configure outlook clients

  - by chrissie1

  I have a prf file to outlook clients. For the moment the new exchange will be in another domain, that will change in the future. But the usernames on both domains are the same. I see that the example prf just takes the username ;*************************************************************** ; Section 4 - Default values for each service. ;*************************************************************** [ServiceEGS] MailboxName=%UserName% HomeServer=exchange_server_name [Service1] OverwriteExistingService=No UniqueService=Yes MailboxName=%UserName% HomeServer=exchange_server_name AccountName=Microsoft Exchange Server Can I add the domainname to that like so. MailboxName=\\domain\%UserName´% or is there a better way of doing this.

• Ubuntu + SSL ports + AVAST

  - by jurajvt

  I have an interesting problem with communication via standard SSL ports. Fresh installed Ubuntu 14.04 server + Postfix + Dovecot, SASL authentication provided by Dovecot, self-signed certificate generated trough the Dovecot script mkcert.sh. Redirected ports on ZyWALL USG 200. I can send and receive e-mails from outside with standard ports 25 and 110, but not over 587. I am connecting to my server from machine with Windows 8.1 + VMWare Player + Ubuntu 14.04 Desktop + ssh. On Windows host I have installed Avast! antivirus. When I am trying to telnet from virtual machine to server over 587, it refused connection. But when I turn on Avast! it let me in to message Connected to... Same with nmap. When Avast! is turned on it is show me all SSL ports. When I turned it off, only standard ports appeared. OpenSSL shows me CONNECTED(00000003). But outside virtual machine directly in Windows 8.1 using nmap with zenmap there are not opened SSL ports in both Avast! states. From other external linux machines are problems with touching SSL ports same - refused. I have turned on submission in master.cf and 587 port is correctly listening on 0.0.0.0 in process master.pid which belongs to Postfix. I can telnet, or nmap over port 587 to my domain directly from server. Other ports like 995, 993 are OK on localhost, too. It is true, that I can't send emails via 587 anyway (Avast! turned on/off), but I can see ports opened. It is possible, that I have simply bad certificate and Avast! has right one, so with turned it on I can see opened ports? EDIT: To be more clear, I can't see or using port 587 everywhere from outside (tried Thunderbird, telnet, openssl, nmap, putty, swaks; both from Linux or Windows machines) and that is my problem. It was only by chance that I saw opened ports when Avast! is turned on.

• Windows TCP timeout

  - by hs2d

  Is there on windows any default timeout for tcp connection? So when no answere is received the connection would be closed. Why im asking is that on one machine the connection is closed afther 5 minutes.(Windows XP) Running the same client - server connection on other machine the connection is kept open forever like it should be. Or maybe there is some global java virtual machine setting somewhere i should know about? The server and client run on the same local machine

• Is it possible with Google searches to ban any and all results from a domain? [closed]

  - by Stu Thompson

  Is it possible to configure Google somehow to permanently ban search results from domains that I know 100% are never, ever going to make me happy? Something cookie/session based maybe? E.g. I want to ban (permanently, forever and always) results from experts-exchange.com. Every time I click results that take me to their page I just want to scream. Update! Google has released a Chrome Extension to allow users to block individual site from Google search results! Personal Blocklist (by Google). (Since this question has been closed, I cannot answer it.)

• Comparing two specific properties of a CSV using Compare-Object isn't giving the expected results

  - by MDMarra

  I have a list of users from two separate domains. These lists are in CSV format and I only care about the SAMAccountName, which is a field in these CSVs. The code that I'm working with is currently: $domain1 = Import-CSV C:\Scripts\Temp\domain1.xxx.org.csv | Select-Object SAMAccountName $domain2 = Import-CSV C:\Scripts\Temp\domain2.xxx.org.csv | Select-Object SAMAccountName Compare-Object ($domain1) ($domain2) This is returning only a handful of results (which aren't accurate) in this format: @{samaccountname=SomeUser} => Obviously, Compare-Object isn't evaluating the objects as strings. How do I make this work?

• Proxy between data centers [closed]

  - by dstarh

  Possible Duplicate: Can IIS be configure to forward request to another web server? We are switching data centers (actually datac-center to EC2 to be specific) and some customers have not yet made DNS changes to point the domains to the new load balancers. We are thinking of leaving the existing servers up and just using a proxy server to forward the request to the new load balancer. Can anyone recommend a good proxy server for doing this I've got squid installed but it seems it's fairly easy to just have a fairly wide open proxy server and we don't want this. I want all requests coming in on port 80 to be sent to port 80 at a specific domain (elastic load balancer) the data center env is windows 2k3 and the EC2 env will all be linux but the ec2 env should be irrelevant

• Ask filesystem if it is mounted

  - by Brian

  How can I see if a (ext3) filesystem is mounted by asking the filesystem directly (i.e. the same way that the system does when it boots and sees that it was not unmounted cleanly)? Checking the output of mount is no good because the filesystem might be mounted by a virtual machine. I know I can run fsck and it will abort if the filesystem is mounted, but I don't need to actually check the filesystem.

• URL not responding on OS X, fine on other machine

  - by Rory Fitzpatrick

  For some reason I can't access anything on python.org. nslookup resolves the IP address, but no browser or curl command will fetch anything. It works fine on a VMWare Ubuntu virtual machine and on a Windows machine on the same network. I've checked there's nothing funny in /etc/hosts I don't know where else to go looking for issues, can anyone suggest anything? Running OS X 10.5 Leopard
