  • Adding a Windows Server 2012 Essentials server to an existing domain, without migrating the AD

    - by TiernanO
    I have an existing Active Directory in house, a mix between a Win2K8R2 and Win2K3 domain, and i would like to test out Windows Server 2012 Essentials BETA on the network. When walking though the install, it gives me the option of a new domain, or migrating from an existing domain. when clicking existing, it tells me i can only have one SBS server running on a domain at a time... So, i dont have any existing SBS servers in house (both are full standard or enterprise editions) but i do plan on keeping at least one of these extra servers running... So, how do i get a 2012 Essentials server to join a domain, and not migrate the existing domain? or if i do migrate, can i still get one of the other boxes to act as secondary controllers?

  • apache returning "The connection was reset"

    - by usjes
    One of my dedicated servers had some network issue today and the data center has to replace some router. Since then the sites on that server returns "The connection was reset" error most of the time. I tried installing nginx and it opens better, but it still shows the error sometimes. Everything in the config seems normal, what could be causing this error? UPDATE: Just noticed that in whm apache status there are always only 1 requests currently being processed, 8 idle workers. I know for sure the server received thousands of requests per minute. What could be limiting this to such a low number?

  • Routing tables don't show ppp0 after 12.04 kernel upgrade to 3.5.0: Haier CE682 modem configuration

    - by ubunsteve
    I'm trying to get my Haier CE682 EVDO modem, model number 201e:1022 to work in ubuntu 12.04 kernel 3.5.0-030500-generic #201207211835 . I had it working in a previous 12.04 kernel, using compat-wireless and these instructions http://zulkhamsyahmh.blogspot.com/2012/05/install-smartfren-haier-ce682-on-ubuntu.html, and to get it working had to edit the routing tables so that there was a ppp0 showing up, as suggested at http://www.linuxquestions.org/questions/slackware-14/wvdial-is-connecting-but-im-unable-to-do-anything-714861/ Network manager doesn't work with this modem, so I use either wvdial or gpppon to connect to it, both which work (after I run the command sudo modprobe usbserial vendor=0x201e product=0x1022 ) This is the output of when I connect with gpppon to the modem: Using interface ppp0 Connect: ppp0 <-- /dev/ttyUSB0 sent [LCP ConfReq id=0x1 ] rcvd [LCP ConfAck id=0x1 ] rcvd [LCP ConfReq id=0x2 ] sent [LCP ConfAck id=0x2 ] sent [LCP EchoReq id=0x0 magic=0x819c86db] rcvd [CHAP Challenge id=0x1 <1ac8f12799e953967a3cc222c9254690, name = ""] sent [CHAP Response id=0x1 <6f12a903dc40915ca2761c17b87f8fbd, name = "smart"] rcvd [LCP EchoRep id=0x0 magic=0x0] rcvd [CHAP Success id=0x1 ""] CHAP authentication succeeded CHAP authentication succeeded sent [CCP ConfReq id=0x1 ] sent [IPCP ConfReq id=0x1 ] rcvd [IPCP ConfReq id=0x1 ] sent [IPCP ConfAck id=0x1 ] rcvd [CCP ConfReq id=0x1] sent [CCP ConfAck id=0x1] rcvd [CCP ConfRej id=0x1 ] sent [CCP ConfReq id=0x2] rcvd [IPCP ConfRej id=0x1 ] sent [IPCP ConfReq id=0x2 ] rcvd [CCP ConfAck id=0x2] rcvd [IPCP ConfNak id=0x2 ] sent [IPCP ConfReq id=0x3 ] rcvd [IPCP ConfAck id=0x3 ] not replacing existing default route via 192.168.3.1 local IP address 10.191.248.154 remote IP address 10.17.95.25 primary DNS address 10.17.3.244 secondary DNS address 10.17.3.245 as you can see there is a problem with "not replacing existing default route via 192.168.3.1" This it the out put of route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.3.1 0.0.0.0 UG 0 0 0 wlan0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.168.3.0 * 255.255.255.0 U 2 0 0 wlan0 I had tried these commands, which had previously worked in the earlier kernel: route del default route add default ppp0 but that broke my wireless internet connection. I then added the default routing as shown above with sudo route add default gw 192.168.3.1 wlan0 So it seems I need to add or change the routing to show a ppp0 connection, but I don't know how to do that.

  • How do I get detailed information about what happens during logon

    - by Funky Si
    Due to my IT department leaving I am now responsible for all our IT systems. I now have several problems to get my head around and fix. I run Active Directory on windows server 2003 and use group policy to apply settings etc. Recently we have had some windows 7 clients added to our network, these are having awful problems with our logon scripts and drive mappings. For the most part my XP clients are working without a problem. What I want to know is what is going on during logon, as running the logon scripts after I have logged on often works. Does anyone know of a way to get detailed log information of what is happening before and during logon. Thanks for your help and any suggestions you have for tracking down the source of these problems.

  • New Linux Mint User Networking questions

    - by nyCecilia
    I have a readynas that I've been using with XP, Vista, and Win7. Because of weirdness with Vista, it is set up for full read/write guest access. Now I have a Linux Mint netbook. I have set up smb on it and can read from the readynas smb shares, but I can't write. What else can I check? Part2--(keep in mind my network knowledge is small...or smaller) what is the difference between NFS and SMB, can a readynas be set up to allow access to the SMB shares via NFS (if I can figure out NFS lol)? A link to a guide for beginners would be appreciated, google searching "Linux Mint Readynas" doesn't give me anything useful.

  • Windows 2008 Domain Controller - Backup (BDC) to Primary (PDC)

    - by Klaptrap
    I have created a new domain controller with my single domain forest. I have also made it DHCP and DNS ready - all 3 services have synchronised with the existing W2K8 domain controller. I even migrated the FSMO roles and thought everything was fine. Indeed all machines on network appear to obtain DHCP and DNS from new server and the AD is working on the new server as my internal website uses it for login authentication. I have just noticed, via BgInfo - Sys Internals - that the new server is showing as "backup" and the old as "primary" - I thought I had already achieved this. Have the FSMO roles swapped back - as I have yet to have removed the old server from AD (dcpromo). Do I need to do anything before I run dcpromo on the old server? Any thoughts appreciated....

  • Need disc image help pronto!

    - by data
    I recently got a job as a junior network administrator. Last week the senior admins did their yearly reinstall of server 2003, exchange, drivers etc on the main server. I've been asked to back up the disc so that next year they can just copy over the pre-made image. What tools can i use to achieve both the creation of the entire servers HDD image and loading it back on (id like to test it in the sandbox.) To impress them, a program that is free is preferable. And maybe a tool that can do it all from booting the program off of a USB drive.

  • Exchange 2010, Exchange 2003 Mail Flow issue

    - by Ryan Roussel
    While performing the initial Exchange 2010 deployment for a customer migrating from Exchange 2003, I ran into an issue with mail flow between the two environments.  The Exchange 2003 mailboxes could send to Exchange 2010, as well as to and from the internet.  Exchange 2010 mailboxes could send and receive to the internet, however they could not send to Exchange 2003 mailboxes.   After scouring the internet for a solution, it seemed quite a few people were experiencing this issue with no resolution to be found, or at least not easily.  After many attempts of manually deleting and recreating the routing group connectors,  I finally lucked onto the answer in an obscure comment left to another blogger.   If inheritable permissions are not allowed on the Exchange 2003 object in the Active Directory schema, exchange server authentication cannot be achieved between the servers.   It seems when Blackberry Enterprise Server gets added to 2003 environments, a lot of Admins get tricky and add the BES Admin user explicitly to the server object  to allow  inheritance down from there to all mailboxes.  The problem is they also coincidently turn off inheritance to the server object itself from its parent containers.  You can re-establish inheritance without overwriting the existing ACL however so that the BES Admin can remain in the server object ACL.   By re-establishing inheritance to the 2003 server object, mail flow was instantly restored between the servers.    To re-establish inheritance: 1. Open ASDIedit by adding the snap-in to a MMC (should be included on your 2008 server where Exchange 2010 is installed) 2. Navigate to Configuration > Services > Microsoft Exchange > Exchange Organization > Administrative Groups > First Administrative Group > Servers 3. In the right pane, right click on the CN=Server Name of your Exchange 2003 Server, select properties 4. Navigate to the Security tab, hit advanced toward the bottom. 5. Check the checkbox that reads “include inheritable permissions” toward the bottom of the dialogue box.

  • Seamlessly Authenticate with a Secondary Active Directory Server (when primary is down)

    - by LonnieBest
    How do you get workstations to (seamlessly) authenticate with a secondary Active Directory server when the primary one is down? Background: I added a secondary Active Directory server to a company's network, hoping that it would do authentication in the event that the primary Active Directory server was down. Although, the Secondary Active Directory server seems to be replicating correctly, authentication doesn't occur while rebooting the primary Active Directory server. Do I have a misunderstanding regarding the role of a secondary Active Directory server, or are there additional settings I must set to get the workstations to authenticate with it when the primary is down?

  • Friday Tips #6, Part 2

    - by Chris Kawalek
    Here is a question about updating Oracle VM: Question: How can I perform Oracle VM 3 server updates from Oracle VM Manager? Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management: Server Update Manager is a built-in feature of the Oracle VM Manager. Basically, Server Update Manager automatically configures YUM updates on all the Oracle VM Servers, pointing each to our Unbreakable Linux Network (ULN) update channel for Oracle VM. The servers periodically check with our Oracle YUM repository and notify the Oracle VM Manager that an update is available for each server. Actual server updates must be triggered by the Oracle VM administrator – they are not executed automatically. At this point, you can use the Oracle VM Manager to put a server into maintenance mode which live migrates all the running Oracle VM Guests to other Oracle VM Servers in the server pool. Once all the Oracle VM Guests have been migrated, the Oracle VM administrator can trigger the update on the server. The entire process is documented in the Installation and Upgrade Guide of Oracle VM Documentation so I won’t spend time detailing the steps. However, configuring the Server Update Manager is exceedingly simple. Simply navigate to the Tools and Resources tab in the Oracle VM Manager, select the link for Server Update Manager and ensure the following values are added to the text boxes as shown in the illustration below: YUM Base URL: http://public-yum.oracle.com/repo/OracleVM/OVM3/latest/x86_64 YUM GPG Key: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle Every server in the pool will be automatically configured for YUM updates once you choose the Apply button. Many thanks to Greg and Rick for providing the answers to this week's questions. If you want to ask us something, hit up Twitter and use hashtag #AskOracleVirtualization. See you next week! -Chris

  • How do I turn a shared computer back into a shared media drive?

    - by Brian Green
    There is an external hard drive that is set up as a shared media device for a TV. I tried to hook up my the library on my desktop as a shared media drive to watch movies from my computer on the TV. It worked for a little bit but about 5 seconds after getting into my computer the tv went blank and I couldn't access the external hard drive any more. When I checked on my computer the Hard drive was no longer a shared media device but now it was a computer on the network. How do I fix this and turn it back into a shared media device so I can access it on the TV?

  • Moving files from Public folder to C: takes a minute, even though they are same hard drive and same

    - by Jian Lin
    I have a big file, like 2GB, and would like to move it from Network -> Bookroom -> Users -> Public (this is the computer in the bookroom in the house) to c:\myfiles and they are actually on the SAME hard drive (and same partition). But copying still takes a minute or so? I thought if on the same hard drive and partition, then it is a "move" and it should take 2, 3 seconds only. that public folder also is \\Bookroom\Users\Public Update: Sorry, I actually mean "move" all the way... so it is not copy but move. So that's why I thought it should take 2, 3 seconds only.

  • Backup SQL server db issue: delete old backup files

    - by David.Chu.ca
    I tried to use sqlmaint.exe tool to back up a database on a remote PC. Here is an example of backup: sqlmaint.exe -S remoteSQLServer\SQLInstance -U username -P pwdxxx -D myDB -BkUpMedia DISK -BkUpDB C:\MSSQL_Backups -DelBkUps 3days ... Here I specified to delete backups older than 3 days. However, the job seems not deleting old bak files on the remote PC(where the SQL server sits). The remote PC has Windows 2008 Server. I also set the C:\MSQL_Backups as shared network drive for EnyOne as owner. My understanding is that the job will delete any bak files older than 3 days. Not sure what I missed? By the way, the job runs at a box with SQL server 2005 installed.

  • How do I require use of the 5 GHz band when connecting to a Wireless N access point?

    - by cqcallaw
    What is says in the topic: there's a Wireless N access point to which I'd like to connect using the 5 GHz band exclusively. How does one accomplish this? Using the directive band=a in the connection configuration file in /etc/NetworkManager/system-connections doesn't seem to affect anything (/var/log/syslog still shows attempts by wpa_supplicant to connect using the 2.4 GHz band), and running iwconfig wlan0 freq 5G per this question results in the following error: Error for wireless request "Set Frequency" (8B04) : SET failed on device wlan0 ; Invalid argument. [Edit] I'm hoping the answer won't depend on the hardware in use, but here's some information about the hardware, just in case: System is an Asus ZenBook Prime UX31A-DB51, running Ubuntu 12.04. lspci output: 00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 00:04.0 Signal processing controller: Intel Corporation Device 0153 (rev 09) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.1 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 2 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Panther Point SMBus Controller (rev 04) 00:1f.6 Signal processing controller: Intel Corporation Panther Point Thermal Management Controller (rev 04) 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24) The driver for the wireless interface is iwlwifi.

  • What Should I Do? [closed]

    - by Laxmidi
    What is a reasonable goal in terms of traffic for my Flex 3 site: www.brainpinata.com Since I began a couple of months ago, I've gotten roughly 5500 ad views and 280 ad clicks. And the ad revenue is a whopping $4.80. (I don't use Google Adsense). I advertise my site using Google Adwords to try to build traffic. My budget is $10/day. What should I do? a) Push the marketing. Add a blog. Try to get backlinks, contact blogs, start a Facebook page, tweet, etc. b) Google is only indexing the static content in the SWF. The questions/answers are pulled from a mySQL database. So, Google doesn't index 99% of the content. Should I re-do the site in HTML/Javascript and hard-code the questions for each puzzle? (This would be a challenge as I don't know javascript worth squat.) Or should I hard-code the questions in XML and put them in the Flex app? If I put the questions in an XML file it's roughly 500 KB. Other ideas? c) Should I switch ad networks? (I currently get about 100 visitors a day). My ad network pays so little that if I were to make even $500/month, I would need 550,000 ad views/month, which seems impossible. If I go ahead and switch ad networks, I need to find one that allows iFrames as I've got a Flex website. Which ad networks permit their ads to be shown in iFrames? d) Should I cut and run? I put a lot of work into this project and it would really stink to get nothing out of it. I'm looking for some good advice. Looking forward to your suggestions. Thank you. -Laxmidi

  • script Disk Management configuration

    - by Joseph
    I have 10 workstations with large monitors that have USB slots and several card readers built in. The card readers cannot be disabled and will map to drive letters when I image the computers. I go into Disk Management and delete the drive mappings and add mappings to a single folder in C:\ with a folder for each slot. I have to do this because of scripts that run that are expecting specific letter drive mappings to network resources. Is there a way to script the deleting and adding of drive mappings instead of having to use the Disk Management GUI manually on each workstation? The workstations are running XP Professional.

  • How to document requirements for an API systematically?

    - by Heinrich
    I am currently working on a project, where I have to analyze the requirements of two given IT systems, that use cloud computing, for a Cloud API. In other words, I have to analyze what requirements these systems have for a Cloud API, such that they would be able to switch it, while being able to accomplish their current goals. Let me give you an example for some informal requirements of Project A: When starting virtual machines in the cloud through the API, it must be possible to specify the memory size, CPU type, operating system and a SSH key for the root user. It must be possible to monitor the inbound and outbound network traffic per hour per virtual machine. The API must support the assignment of public IPs to a virtual machine and the retrieval of the public IPs. ... In a later stage of the project I will analyze some Cloud Computing standards that standardize cloud APIs to find out where possible shortcomings in the current standards are. A finding could and will probably be, that a certain standard does not support monitoring resource usage and thus is not currently usable. I am currently trying to find a way to systematically write down and classify my requirements. I feel that the way I currently have them written down (like the three points above) is too informal. I have read in a couple of requirements enineering and software architecture books, but they all focus too much on details and implementation. I do really only care about the functionalities provided through the API/interface and I don't think UML diagrams etc. are the right choice for me. I think currently the requirements that I collected can be described as user stories, but is that already enough for a sophisticated requirements analysis? Probably I should go "one level deeper" ... Any advice/learning resources for me?

  • How do I set up different configurations on an Ubuntu laptop based on different physical locations?

    - by Andrew Larned
    I'm looking for a way to have a couple (or three) multiple configurations set up on my laptop, and easily switch between them. To be more specific, when my laptop is at work, it's plugged into a second monitor, and has a specific set of networks configurations. At home, the second monitor is gone, the network configurations are different. At a public wireless point there are other configurations to set, etc. I know I can go into my preferences and turn on/turn off the monitor, and mess with the networking preferences, and so on, but I'm looking for a way to change a bunch of preferences all at once, and if it's possible to do that automatically, maybe based on the wireless APs in the vicinity, that would be even better.

  • OS X 10.8.3 + attempt to change VPN settings = no more VPN access

    - by nicole
    I am running Mountain Lion and had gotten very tired of re-entering my password at random times when using my school's VPN network (I don't know much about these, but the type is Cisco IPSec according to the setup instructions I followed a while back). In an attempt to make life easier, I followed the instructions here, but, alas, any attempt to connect with VPN was met with the message "A configuration error has occurred. Verify your settings and try connecting again" (or something along those lines.) I then tried to do the steps in the blog post in reverse and change everything back. Upon (supposedly) doing that, though, a new error message came when attempting to connect to VPN: "The negotiation with the VPN server failed. Verify the server address and try reconnecting." Now I have no idea what to do. Is there a way to reset all VPN-related things in my system so that I can follow my school's instructions and just start over?

  • 12.10 Wireless hotspot configuration and internet browsing - question

    - by Indian
    In our campus we have a leased line connection from a service provider, which has an external IP W.X.Y.Z. This connection is distributed from the server several sub-networks / subnets as follows: Faculty: 172.33....../ 255.255.0.0 Administration: 172.34......./255.255.255.0 Students: 172.35...../255.255.216.0 A student has a laptop with a fixed IP address 172.35.23.123 / 255.255.216.0 where the IP address is on the ethernet port. The gateways for internet access are 172.31.1.1 and 172.31.1.2. Further the student has a wireless port which is inaccessible in the hostel area. The OS of the student is Ubuntu 12.10. The student in the possession of an android phone on which he wishes to install specific software and therefore wishes to activate the internet therein.
