• MS 2008 R2 Drops Remote Desktop Sessions in 10 seconds or less every time

  - by mike42

  I'm adding a new 64-bit server to our domain. Everything seems fine except when accessing the machine using remote desktop, after a few seconds the connection is lost. The error message is "This computer can't connect to the remote computer." "Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator." A similar result with Telnet on port 3389. I am able to connect but if I hit a key the connection to host lost. The event log shows the successful login. No errors. Any ideas?

• Our company has 100,000s+ photos, how to store and browse/find these efficiently?

  - by tobefound

  We currently store our photos in a structure like this: folder\1\10000 - 19999.JPG|ORF|TIF (10 000 files) folder\2\20000 - 29999.JPG|ORF|TIF (10 000 files) etc... They are stored on 4 different 2TB D-link NASes attached and shared on our office network (\\nas1, \\nas2, and so on...) Problems: 1) When a client (Windows only, Vista and 7) wishes to browse the let's say \\nas1\folder\1\ folder, performance is quite poor. A problem. List takes a long time to generate in explorer window. Even with icons turned off. 2) Initial access to the NAS itself is sometimes slow. Problem. SAN disks too expensive for us. Even with iSCSI interface/switch technology. I've read a lot of tech pages saying that storing 100 000+ files in one single folder shouldn't be a problem. But we don't dare go there now that we experience problems on a 10K level. All input greatly appreciated, /T

• Access denied for user 'root@localhost' (using password:NO)

  - by murgatroid99

  I am attempting to install a network management package called cacti onto Ubuntu running under Windows Virtual PC. I attempted to install MySQL as it is one of cacti's dependencies. I can install and start the MySQL server, but whenever I try to access it in any other way, such as to change the password, I get the error message Access denied for user 'root@localhost' (using password:NO). I would like to know what is causing this and how to fix it. Edit: (just in case my comments are not visible) The answers from HD and Devin Ceartas did not work for me.

• How to change the clients and "My Documents" from a SBS2003 server to a new SBS2008 server?

  - by Sanoj

  Today we have a small network with 5 clients and a Windows SBS 2003 as a server. Now have we bought a new server with Windows SBS 2008. How do I easiest: Switch the clients working with the old server, to work with the new server? Is it just to run http://domain/connectcomputer again? Move the data in "My Documents" from the old server to the new server? And finally, is there anything other that I have to think of when changing server? It will be a new clean installation.

• Domain in a hosted environment

  - by cpgascho

  We have an application we host in a third party data center for our clients. We have multiple clients running the same application on several racks of servers. Most of our clients require that our servers be SAS70 compliant. Currently each server has it's own set of users and security settings that need to be configured. We are creating scripts to do this, but what would be the risks/advantages of joining all the servers to the domain for User Management and Group policy for enforcing security settings? The rational of some is that if the DC is hacked the whole network would be compromised where as if one stand alone hosted server is hacked everything else should be safe.

• Windows W8, L8 and now H8

  - by raccoon_tim

  Windows 8 is having to endure with a lot of headwind at the moment. The weather forecast doesn’t appear to improve in the near future either with prominent game developers and publishers taking to the barricades accusing Microsoft of building a closed ecosystem. I am forced to side with this opinion as I too see services the likes of Steam as playing an important role in the gaming world, which just happens to be an industry that cannot be sidelined. What Microsoft is attempting to do is merge the PC and mobile markets. The Windows Marketplace is to be the only place where you can purchase Windows applications in the future starting now with Metro apps. This is what Apple, Google and Microsoft have been doing with mobile devices for some time now and it’s what we have all come to expect. The PC market is different, however. It has always been open, which has resulted in a diverse market allowing for third parties to build successful distribution and marketing networks. You could argue that Microsoft is just doing something that Steam has been doing for a long time now but the difference is that Microsoft would own both the marketplace AND that operating system, which would eventually give it dominance over the whole Windows application distribution network. Currently there is no real alternative to Windows in the PC gaming world but I would expect to see Mac OS and Linux getting more popular if Microsoft does not notice the signals coming from the gaming industry and choose to once again open up the markets on the PC.

• Moving to Data Center

  - by Won

  Please, give me any advice. Our company has decided to move servers to a data center since we are having a major network traffic jam. The data center provides 100MB bandwidth and full 42 unit cabinet for us. Right now, I am planing to have two firewalls for a failover and changing DNS informations for a web server. Is there anything that I have aware of before I move them to the data center? 1. Web Server 2. Exchange Server 3. SQL Servers

• connected ethernet without disabling wireless, now I have *two* LAN ip's?

  - by peter karasev

  Ok I'm on ubuntu 11.04, not too knowledgeable about network stuff. Usually people ask things like "wired works but wireless does not!". In m y case, I'm just curious about what it means to have both of them seemingly connected. In 'ipconfig' in shell I see that I have 192.168.1.2 for the wireless AND 192.168.1.3 for the ethernet. What does this mean for applications, does one of the two get precedence? It seems like my pages load slightly faster, so perhaps the ethernet is being used, but I could be imagining the speedup...

• Internet Connectivity... Help please!

  - by James

  Hi. My Laptop is having trouble connecting to my wireless router. Other laptops are using the wireless, but it's not reached capacity. The laptop recognises (with a strong signal) that there is wireless internet, and I can connect via the router with a cable because this happens automatically. My problem is this... When I click "connect" (for example in the network and sharing centre), the dialogue box closes and nothing else happens - as though "connect" is being read as "exit". I am running Vista on a Toshiba Satellite Pro P300. Any help would be very much appreciated, Thanks

• safe to setup NAS in virtual image with web server?

  - by Erik

  My current setup is Ubuntu Desktop, running Apache + MySQL + PHP stack. I use this image to host my small website to the outside world. I want to now run a virtual machine on the box, that will act as the FreeNAS box for my internal network. This sounds like a bad idea if the website gets hacked/attacked. Should I just give up and grab a dedicated machine instead? Can I instead virtualize the web server and NAS side by side on this machine?

• How to get a windows domain server to recognize a linux machine by its name?

  - by CaCl

  In my company I ran into an issue where we have a linux machine that serves up a Subversion repository. Its hooked up via LDAP to the Active Directory. We got an account setup for an application and they set the Limited Workstations up so it didn't have full access to the network. The problem is that even though the hostname for our machine resolves correctly for me, the credentials for the application account seem to come back as not being allowed based on the name (the error was related to authorized workstations). I don't have access to any of the domain servers but it might be helpful to come at the management or high-level techs with some ideas, they don't seem to have a solution besides allowing all workstations for the user. Does anyone have any idea on how to get my linux machine to properly identify itself with the Domain machine by name?

• How to attach multiple ipv6 ips to eth1 on debian

  - by Noodles

  I've just got a new server with native ipv6. I want to attach multiple ipv6 ips to eth1, but the only way I can see to do so is to attach them individually: i.e. address 2607:f0d0:xxxx:xxxx::2 address 2607:f0d0:xxxx:xxxx::3 address 2607:f0d0:xxxx:xxxx::4 Is it possible to bind whole subnets of ipv6 to a single network interface on debian? My server host tells me I have 18,446,744,073,709,551,616 ipv6 addresses for that server, surely it gets to be a nightmare to manage if they all have to bound individually (plus ifconfig would look messy). Does anyone have a solution?

• /etc/hosts file for a multi-homed, multi-domain machine?

  - by threecheeseopera

  I have a server (debian) with two network interfaces that I would like to host multiple services and domains on; it is not entirely clear to me how the hosts file should be set up. Example: eth0, bound to WAN interface 1.2.3.4: mail.example.com www.example.com eth0:1, bound to WAN interface 1.2.3.5: www.other-domain.com eth1, bound to LAN 192.168.1.123: some-clever-hostname What should my hosts file look like? (including localhost,localhost.localdomain, etc.) Should I use DNS for some of these entries? Which ones? Thanks!

• Unable to connect to vrde virtualbox VM remotely

  - by b1ackjosh

  So I've remotely created my first headless using ssh. Now I'm attempting to connect to this VM using RDP so I can install Ubuntu Server, but I cannot get connected at all. When starting the VM everything appears fine: $ vboxheadless -s WebTesting Oracle VM VirtualBox Headless Interface 4.0.16 (C) 2008-2012 Oracle Corporation All rights reserved. VRDE server is listening on port 4455. And showvminfo shows: VRDE: enabled (Address 0.0.0.0, Ports 4455, MultiConn: off, ReuseSingleConn: off, Authentication type: null) However I'm still prompted with the "enter your credentials" screen every time I attempt to connect. From reading the documentation null shouldn't prompt me with this screen at all... Any help with this is greatly appreciated. P.S. I am using ssh tunneling in putty to tunnel in to my network.

• Enterprise Data Center System Admin/Engineer to Server Ratio

  - by Bob

  I know there have been similar questions asked over the last few months however looking at a Data Center Operations and know there are some really smart people out there that might be able to help. Looking for some staffing best practices based on first hand experience and was hoping that there is some experience in this area that can provide "best practice" application: Three High Availability (99.99% plus) Enterprise Level Data Centers geographically dislocated, one manned 24x7x365, one lights out, one co-location running HOT-HOT-HOT supporting a global community. More than 2,000 operating systems consisting of 95% Windows, 5% Linux and Solaris, 45% virtualized, more than 100TB storage. No desktop support, no Network Administration (administrated separately), running N+1 and serving more than 250 Billion page views annually. Based on experience what has been your experience with Server to "Data Center System Administrator/Engineer" ratio? Thanks in advance for your responses.

• Synced audio ouput on multiple machines? VLC? hardware solutions?

  - by zimmer62

  I'm wondering if there is any software or hardware solutions to synced audio or audio and video across multiple computers or devices on a network. I've seen Sonos, and it might be a good solution, but it's also a very expensive solution. I'd like to be able to play something with realtime audio output on one PC, but hear it on speakers throughout the house, being it the home theater receiver, or another computer in another room. I saw a solution using the apple iport express, but the latency was unacceptable for anything other than just music. I'd like to avoid running audio wires with baluns to a bunch of amplifiers scattered all over the place when I have cat5 run everywhere. Is anyone familiar with using this kind of process for whole home audio? The latency is a big deal for me, if I've got video attached to the sound (e.g. watching a hockey game)

• Is there a way to get a shared spreadsheet to update without closing and reopening?

  - by Mike

  Using Excel 2010, I have a spreadsheet that is used by 3 different people at any one time. But if one person has the spreadsheet open on there PC the other people can only view it as read only. I have since shared the workbook and put the spreadsheet on a shared network drive and now they can all view the spreadsheet at the same time and edit it at the same time. The problem is that nobody can see the changes that the other users have made unless the close out of the spreadsheet and open it up again to view the changes. I have checked the settings of the shared workbook and on the advanced tab have tick the option that updates the information every 5 minutes but the information does not update until you close out and open the spreadsheet back up again. How can I fix this problem?

• Opensolaris, ZFS shares

  - by Random

  I've recently updated to OpenSolaris 2010.05 from 2009.06. Its currently set up to share one of the the ZFS zpools to the other machines on my network. However, only a single account is able to access these shares. My other accounts get refused when attempting to connect. File permissions are all correct - When logging into the machine directly with the other logins, I can see, and play with the files and directories as normal - Its just the share that gets refused. The interesting thing is, I could access the shares prior to upgrading. Nothing else was changed other than the straight upgrade. I am pretty sure there is no user specific sharing going on. What could be preventing others from accessing this zpool?

• Why no final dot for domain names?

  - by user41150

  I recently learned that a fully qualified domain name ends in a dot, e.g. www.microsoft.com.. Why do I almost never see this? We casually toss around www.microsoft.com, a relative domain name, without a second thought. It's not mere pedantry, because it seems there's a security issue: someone in your network could create www.microsoft.com.example.com. to hijack your requests to www.microsoft.com. Why doesn't the internet community have a tradition of using genuinely fully qualified domain names?

• How to forward traffic using iptables rules?

  - by ProbablePattern

  I am new to iptables and I have been doing Google searches for a few days now without finding a good solution to this problem. I have computer A with a public ip address (say 192.0.2.1) that can access the Internet unrestricted. I have another computer B with a private ip address (192.168.1.1) that can only access computer A. How do I use iptables to forward network traffic from B through A to the Internet? I need to use http, ftp, and https in order to use apt-get with sudo. Both computers run Ubuntu linux. I have tried using Squid but I think it is far too complicated for what I need to do.

• Windows 7 system CPU bogged by windows services, no explanation

  - by Alex

  I'm looking at a laptop for a colleague which is running terribly slow. A quick look showed that the CPU was 100% used by 2-3 SVCHost processes, which off course doesn't tell much since those are just 'cover' processes with services running underneath them. So I fired up process explorer in hopes of finding a shady rogue service which was bogging the system, but to my suprise I found genuine MS Windows processes (or at least damn-good disguised ones) are bogging down the system: dnscache (DNS Client) IKEEXT (IKE and AuthIP IPSec Keyring modules) iphlpsvc (IP Helper) Seen separately, these processes might seem odd to be using a lot of CPU, but taking a step back one can conclude that all three services are quite closely related to networking. I've tried running: netsh int ip reset log.txt which has helped me save bizarre network-related problems in the past, but this didn't help Off course I though about a virus, but both MS Security Essentials as well as malwarebytes (let both run a full scan).

• How to connect to VPN using commands in Linux (Fedora 16)

  - by WarFox

  Usually, I use the network connections icon on the top bar to connect to VPN. The connection is configured properly and it connects well. Configuration screen shot is given below. As you can see I have selected the 'Connect automatically' option. But this option doesn't help in connecting to VPN automatically upon login. This is my university VPN and it uses 'Point-to-Point encryption (MPPE)' for authentication I need to connect to the VPN using command line, so that I can write a script and run it at start up, so the connection is automatically established every time I login. This will also help in connecting to VPN when I login from 'init 3' mode. I depend on this VPN connection for my internet access. Please help me with the required commands.

• Upgrade from 10.04 to 10.10 on netbook: now or later?

  - by jbatista

  I began with installing 9.04 in a netbook (Asus EeePC 1000H), upgraded to 9.10 and have now Lucid Lynx 10.04 (LTS). Most things tested run pretty good, with the most notable exception being wireless network due to the hardware which I first tested after the last major upgrade and a few times before giving up (failed to maintain connection to WPA2 networks). Other nuisances are not as important (e.g. some hotkeys work, a couple of them don't), but given that most everything works I'm concerned with doing an upgrade to find most things have been broken and I have to go back and dig up on how to get it to work... Once in a while, I look up for some posts elsewhere to read up on problems and to find out if they're tame enough to justify an upgrade to 10.10. I'm not in a rush, but I'm not interested in being too left behind some time from now that an upgrade becomes too costly or downright impossible (many things formatted too differently). I'm not even sure if it's possible to "easily" upgrade from LTS to LTS release... Therefore I ask if it's (in principle) possible to skip releases and only do a major upgrade much later on. For example, is it possible (or advisable) to do an upgrade only when the next LTS comes out (a couple of years from now)? Or is it preferable not to skip releases at all?

• Adding Command-Line Switches To Windows Shortcuts

  - by jaytea

  Is there a way to, in general, create a Windows shortcut to a file and instruct Windows to pass certain switches to the application before passing the filename? For example: I have an Excel file, abc.xlsx. If I want to create a shortcut to open this file read-only, I would change the target to "C:\Program Files\Microsoft Office\Office12\EXCEL.EXE" /r abc.xlsx, but this fails when another person on my network opens the shortcut and their EXCEL.EXE is not in that same folder. Surely there's a way to tell Windows to pass the /r switch without supplying the path/filename of the application that is supposed to open the file?

• Upgraded to Mountain Lion, now 127.0.0.1 is not resolving

  - by Shanimal

  I used to be able to type 127.0.0.1 (or my network IP 10.10.53.32) and it would resolve to my "default" virtual host. 127.0.0.1/~Shanimal and shanimal.dev both resolve to their appropriate folders. localhost and 127.0.0.1 give me a 404 - "Not Found The requested URL / was not found on this server." Basically, my "It works!" screen no longer works. /private/etc/apache2/Shanimal.conf: <Directory "/Users/Shanimal/Sites/_www"> Options Indexes Multiviews AllowOverride AuthConfig Limit Order allow,deny Allow from all </Directory> hosts: 127.0.0.1 localhost 127.0.0.1 shanimal.dev
