• Long access time for static web page on virtual machine

  - by Karol

  My setup Windows 7 on workstation that I use at work (with domain) and home (no domain) Virtual machine (VMWare) that runs Arch Linux (I will call it just "Linux") with network interface in bridged mode. Linux serves web pages with Nginx. IP address of Linux machine is 192.168.0.16 and is added to C:\windows\system32\drivers\etc\hosts: 192.168.0.16 bridged bri IP address of Windows workstation is added to /etc/hosts: 192.168.0.10 workstation I can add more details to my setup description (I am not sure what is relevant). The question Often (but not always) it takes long time for a web browser (Firefox) to open static web page served by Linux. I am sure it is not a performance issue. To be more specific: it takes about ~20 seconds to resolve(?) the address http://bridged for a web browser. Additionally I have just installed samba service and noticed similar problem, so it is not specific to browser & http. Initial access for samba shares also takes long time.

• Reasonable automatic HTML to PDF conversion (in UNIX/Linux environment)

  - by Alex Balashov

  Is there a way to generate PDF documents from HTML files automatically in Linux where the PDF offers some kind of reasonable level of resemblance to the input file? A command-line tool - as opposed to an interactive GUI of some kind - is key. I have tried htmldoc and some related cousins, of course. But these tools are hopelessly stone-age; htmldoc doesn't support CSS at all. You won't find a lot of HTML documents these days that don't have at least some CSS styling. I don't really care about stupid effects or minor embellishments, but the issue is that CSS is at the core of most layouts these days; not many folks are using 6 layers of nested tables anymore. So, if the conversion tool has no grasp of CSS whatsoever, it's not just a matter of "the document doesn't look quite right"; it is likely to not meet the minimum standard of usability at all. It has been suggested to me by some folks to try to use the Gecko rendering engine to generate images that can be converted to PDFs, but I have no idea how one would go about doing this, let alone easily. I have no trouble believing that there are good commercial tools that do this, but I'm really looking for an open-source package if possible, as the endeavour itself is an open-source one and doesn't pay. Thanks in advance!

• Incorrect directory permissions with OpenSSH on Cygwin on Windows Server 2008 SP2

  - by Davy Brion

  I ran into a weird directory permission problem when logged in to a Win2008SP2 (not R2) server through SSH. When I open a local cygwin shell on the server, i can do this: myUser@myServer ~ $ cd /cygdrive/c/Windows/System32/inetsrv/ myUser@myServer /cygdrive/c/Windows/System32/inetsrv $ cd config myUser@myServer /cygdrive/c/Windows/System32/inetsrv/config $ I have no issues accessing the 'config' directory when using a local cygwin shell. 'myUser' has all necessary permissions to access the directory as well. In fact, 'myUser' is a local administrator on the machine. Listing the permissions of the config folder through the local cygwin shell shows the following output: 4 drwx------+ 1 SYSTEM SYSTEM 0 Aug 2 09:38 config But when I log into the server with a SSH client (in this case Putty), i run into the following problem: myUser@myServer ~ $ cd /cygdrive/c/Windows/System32/inetsrv/ myUser@myServer /cygdrive/c/Windows/System32/inetsrv $ cd config -bash: cd: config: Permission denied It also doesn't list the proper permissions through SSH: 0 drwxr-x--- 1 ???????? ???????? 0 Aug 2 09:38 config When I look at the running processes on the server with Task Manager (with a remote desktop connection), it shows that all bash.exe processes are running under the 'myUser' account, so I don't understand why I can't access that particular directory through SSH but have no problems accessing it in a local cygwin shell. I'm using OpenSSH 5.9p1-1. I'm not sure what the Cygwin version is... I used the latest setup.exe (version 2.738) of Cygwin, but I can't seem the find any other Cygwin-related version number. I doubt that it's related to SSH/Cygwin though, because when I connect from the Win2008SP2 server to my local Win7 machine through SSH (using the same OpenSSH/Cygwin versions) I can access the /cygdrive/c/Windows/System32/inetsrv/config folder without issues. Does anyone have an idea on what the issue could be?

• How to forceably unmount stuck network share in Mac OS X?

  - by Kyle Lowry

  Not long ago my Xserve failed (power loss) while an iMac was working with files on a particular network share (called "Work Share"). This volume, "Work Share", is now stuck. It can't be seen in the GUI, you can only detect it using the Terminal. Even after power cycling over the course of several days, ls -a still shows that it's there, but I can't unmount it using any command - not even as root in single user mode. Every time I attempt to unmount that volume, I get the message that the resource is busy (which it can't possibly be since nothing is using it), and error code 4915. The issue is that when I mount the real "Work Share", it internally is renamed to "Work Share-1", which breaks all my links, and several files in the share. If I can't unmount the false "Work Share", then that computer would be unuseable without a reformat, I would imagine - and I don't want it to have to come to that. I've tried everything I can think of - it looks like sudo can't save me now. Any ideas on how to unmount this stuck volume?

• Exchange server issues - can't upgrade to SP3 - trying to migrate to Exchange 2010

  - by Keith

  Our Exchange server is having a lot of issues. It can't get Windows Updates anymore (error 8000FFFF) and it has a lot of other issues that are all related (Server Manager error - Catastrophic failure exception hresult 8000FFFF). Everything I've read online about it says you pretty much have to re-install Windows to fix it. Because of that, we are going to migrate to a new server running Exchange 2010. I have the new server ready and I was doing the pre-requisite checker and it was complaining that the Exchange 2007 installation wasn't SP2 or newer. I checked and indeed, it is SP1. So I am trying to upgrade the Exchange 2007 installation to SP3, however, it is failing. It is hanging on "Removing Exchange files." I followed these instructions and it's still not working. I can get to the part where you run the upgrade from command line but it starts asking for the exchangeserver.msi file. I point it to where it is located but it keeps asking for it. I am starting to get concerned that I can't upgrade the Exchange server because of the same issues above. My next step is to call Microsoft about the issue because I need to get it fixed however I wanted to check here first.

• Verify client certificate CN in Tomcat(APR)

  - by Petter

  I'm running a tomcat installation with the APR libraries installed (with the OpenSSL HTTPS stack that comes with it). What I'm trying to do is to lock a specific HTTPS connector down to users of a specific certificate. Adding client certificate verification is no issue, but I can't get it to validate against a specific Common name only. I was perhaps a bit naïve and thought the mod_ssl attribute SSLRequire typically used in Apache Httpd would work, but that property is not recognized by the Tomcat implementation. (http://tomcat.apache.org/tomcat-7.0-doc/config/http.html#SSL%20Support points to some mod_ssl docs, but the Tomcat implementation does not seem to cover all aspects of mod_ssl). I can get this to work by using the Java version of the connector instead of APR (losing some performance) and just add a trust store with that one certificate in it. However, using openssl without the SSLRequire expressions, I'm not sure how to do this with Tomcat7 (on Windows if that matters). <Connector protocol="HTTP/1.1" port="443" maxThreads="150" scheme="https" secure="true" SSLEnabled="true" SSLCertificateFile="mycert.pem" SSLCertificateKeyFile="privkey.pem" SSLCACertificateFile="CABundle.pem" SSLVerifyClient="require" SSLProtocol="TLSv1" SSLRequire="(%{SSL_CLIENT_S_DN_CN} eq &quot;host.example.com&quot;)"/> Can you suggest a way to make this work using Tomcat/APR/OpenSSL?

• Using Windows Explorer, how to find file names starting with a dot (period), in 7 or Vista?

  - by Chris W. Rea

  I've got a MacBook laptop in the house, and when Mac OS X copies files over the network, it often brings along hidden "dot-files" with it. For instance, if I copy "SomeUtility.zip", there will also be copied a hidden ".SomeUtility.zip" file. I consider these OS X dot-files as useless turds of data as far as the rest of my network is concerned, and don't want to leave them on my Windows file server. Let's assume these dot-files will continue to happen. i.e. Think of the issue of getting OS X to stop creating those files, in the first place, to be another question altogether. Rather: How can I use Windows Explorer to find files that begin with a dot / period? I'd like to periodically search my file server and blow them away. I tried searching for files matching ".*" but that yielded – and not unexpectedly – all files and folders. Is there a way to enter more specific search criteria when searching in Windows Explorer? I'm referring to the search box that appears in the upper-right corner of an Explorer window. Please tell me there is a way to escape my query to do what I want? (Failing that, I know I can map a drive letter and drop into a cygwin prompt and use the UNIX 'find' command, but I'd prefer a shiny easy way.)

• Migrateing to Windows Server 2008 R2 Domain Controllers - a few Questions/Issues

  - by Chris

  Ok so here's our setup: We have 2 Windows2k3 Domain Controllers. I am trying to replace them with Windows 2008 R2. The Win2k3 servers are DC01 and DC02. The Windows2k8 servers are DC1 and DC2. I prepared the Windows Server 2003 Forest Schema for a Domain Controller That Runs Windows Server 2008 or Windows Server 2008 R2. Then with both of the new servers up as member servers I dcpromo'd DC1 using the advanced option and added it successfully to my exisiting domain. Roles are GC, DNS and Active Directory Domain Services.I transferred The PDC, RID pool manager and Infrastructure master FSMO to the new DC.(DC1) The Schema master and Domain naming master are still on the old DC (DC01). The first issue I'm encountering is when i dcpromo the second DC (DC2) and select "Replicate data over the network from and existing domain controller" I select the new DC to replicate from (DC1) I get the following error: "Failed to identify the requested replica partner (dc1.xxx.org) as a valid domain controller with a machine account for (DC2$). This is likely due to either the machine account not being replicated to this domain controller because of replication latency or the domain controller not advertising the Active Directory Domain Services. Please consider retrying the operation with \dc01.xxx.org as the replica partner. "The server is unwilling to process the request." Is this because the Schema master and Domain naming master roles are still on the old DC (DC01)? And if so, if I transfer Schema master and Domain naming master roles to DC1 what is the risk or breaking my AD? I'm a little paranoid because this process HAS to be transparent. ANY down time or interruption will result in me getting a verbal ass kicking from my I.T. Director. Both of the new servers DNS point the the old DNS servers (DC01 and DC02) not themselves by the way. Thanks in Advance -Chris

• Server 2003 Terminal Services Printers not redirecting, no sessions created.

  - by mikerdz

  Ok, odd scenario on a Windows Server 2003 Server Standard running as Terminal Server. Friday, installed 2 new Windows 7 machines to replace older XP machines. After adding these machines and their local printers, none of the otehr 16 Windows 7 machines can redirect printing to the server. I have checked Global Policy on domain controller, nothing is being blocked. In Terminal Services Manager, the client settings are set to User Client Settings. On RDP client, port redirection is enabled. I have tried disabling the Use Client Settings option and manually selected the options for print redirection and default printer connection, but still does not work. After some reaserching, I found this MS article: http://support.microsoft.com/kb/2492632 I went ahead and added the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\fEnablePrintRDR DWORD that the article references and set it to "1" to enable the option. I restarted the server, but still would not print. I am getting quite desperate with this issue because nothing seems to have changed when installing the two new clients and printers. I uninstalled the print drivers for the printers from the server. I have even gone as far as connecting each of the printers manually via UPD (\computername\printer) but even thought it works, it prints awfully slow. Please help!!!!

• Pure Terminal Server 2003 system hangs

  - by Donovan

  System Profile: IBM Server hardware Windows Ent Server 2003 running terminal services. No Citrix. Max user load: 30 Symptoms: While in the course of normal operation our terminal server will hang up. As far as I can tell there isn't any trigger that's plainly visible yet. The way in witch it hangs may give a clue though. The hang presents its self by users not being able to initiate any new processes. All processes currently loaded into memory work just fine. Example: outlook 2007. You may continue to read email, operate the client and such. Some people don't even realize the hang has occurred for a bit of time. My attempts to troubleshoot have been futile. Reacting to the hang does no good because I can't start any new processes to investigate. After I reboot the server my next instinct would be to begin logging to catch the hang occurring but I'm not sure what to log. Right now I'm attempting to keep process explorer running in case the issue occurs again. Sometimes it happens twice a day, other times, once a week. Anyone have any ideas on how I could set myself up for better success in tracking this problem down? Thanks, Donovan

• Google Chrome doesn't delete my browsing history correctly

  - by Derfder

  I have deleted everything that I could from my browser history: chrome://settings/clearBrowserData I checked everything and select the begining of time Then when I access browsing history: chrome://history/ There is nothing (as I expected), or to be precise No history entries found. The problem is that I still see my specific search url with very specific query I have made a month ago, when I start typing the url of the website into chrome address bar. How is that possible? Where is Google stroing these data. How to get rid off them completely? I want to mention that my autosuggestion options look like this: So, what else should I delete to remove everything from autosuggestions? Right now it has some specific URLs (subpages, pages with very specific search query I have made in a month or so). I have tried restarting Chrome and restarting my computer, but the urls are still in the autosuggestion. Also I am unable to turn off the autosuggestion, even I have unchecked that option in settings. My Google Chrome version is: Version 27.0.1453.116 m (probably the latest) Btw. in Firefox deleting the history works as expected. So, I guess that this has nothing to do with the operating system I am using (Windows 7), but only it's an issue with Chrome itself.

• Prevent outgoing traffic unless OpenVPN connection is active using pf.conf on Mac OS X

  - by Nick

  I've been able to deny all connections to external networks unless my OpenVPN connection is active using pf.conf. However, I lose Wi-Fi connectivity if the connection is broken by closing and opening the laptop lid or toggling Wi-Fi off and on again. I'm on Mac OS 10.8.1. I connect to the Web via Wi-Fi (from varying locations, including Internet cafés). The OpenVPN connection is set up with Viscosity. I have the following packet filter rules set up in /etc/pf.conf # Deny all packets unless they pass through the OpenVPN connection wifi=en1 vpn=tun0 block all set skip on lo pass on $wifi proto udp to [OpenVPN server IP address] port 443 pass on $vpn I start the packet filter service with sudo pfctl -e and load the new rules with sudo pfctl -f /etc/pf.conf. I have also edited /System/Library/LaunchDaemons/com.apple.pfctl.plist and changed the line <string>-f</string> to read <string>-ef</string> so that the packet filter launches at system startup. This all seems to works great at first: applications can only connect to the web if the OpenVPN connection is active, so I'm never leaking data over an insecure connection. But, if I close and reopen my laptop lid or turn Wi-Fi off and on again, the Wi-Fi connection is lost, and I see an exclamation mark in the Wi-Fi icon in the status bar. Clicking the Wi-Fi icon shows an "Alert: No Internet connection" message: To regain the connection, I have to disconnect and reconnect Wi-Fi, sometimes five or six times, before the "Alert: No Internet connection" message disappears and I'm able to open the VPN connection again. Other times, the Wi-Fi alert disappears of its own accord, the exclamation mark clears, and I'm able to connect again. Either way, it can take five minutes or more to get a connection again, which can be frustrating. Why does Wi-Fi report "No internet connection" after losing connectivity, and how can I diagnose this issue and fix it?

• Issues with creating a snapshot

  - by Andy Welcomer

  Hello everyone, We have a strange issue when attempting to create a snapshot in one of our regional environments. We have 4 VMs, 2 of them have mulitple VMDKs spread onto different datastores. When a snapshot is created, all the VMDKs (except for the first), seem to vanish. If you look at the properties of the VM, the path to the VMDKS points to the datastore where the primary VMDK is, and the file name is some random garbage. If the snapshot is deleted everything returns to normal. Has anyone ever seen this? I'm using ESX3.5 Thank you in advance. Andy ==============UPDATE============== Here is some more information. I just created a test machine with 7 VMDKs. 1 for the OS. and 6 others for data. All of the VMDKs are in seperate datastores. I take a snapshot of the machine, all of the 6 VMDKs loose their reference to the actual VMDK files. The all point to 64KB VMDK files in the datastore where the OS VMDK is located. These 64KB vmdks didn't exist until the snapshot was taken. When the snapshot is deleted, everything goes back to normal.

• How can Standard User change file associations in Windows 2000?

  - by Gary M. Mugford

  One of my clients is still running Win2K server with a host of Win2K workstations. And no net admin, due to the downturn of the economy over the years. I'm sort of helping out. Out of my depth, but I am a loyal foot soldier. A problem I encounter rather too often is a user double-clicks on a file in Explorer and then either gets no action, or the wrong program to run. It's a case of a missing or out-of-date file association. The current cure is to temporarily upgrade the user from Standard to Power, do the FA switch and then change back. As Winnie would whine, 'Oh, bother!' At any rate, I thought I'd ask here. Is there a method/program to run without the rigamarole FROM the Standard Users account on the workstation to edit/add a file association? I assume the program route would involve RunAs. I 'believe' most of the workstations run the RunAs service, but I could be wrong. I understand that's required, if there is to be a solution. Any help accepted with thanks. GM NOTE: Seems wassociate from http://www.xs4all.nl/~wstudios/Associate/index.html can resolve the issue.

• Managing ip6tables (or an alternative firewall) remotely

  - by Matthew Iselin

  I'm working with IPv6 and have run into an issue configuring ip6tables on our main router in order to control what can come into the network. A default DROP rule in the FORWARD section has worked well (obviously leaving ESTABLISHED,RELATED as ACCEPT) to keep internal clients' open ports from being accessed. However, running an ip6tables command for every little change is unwieldy. Whilst we are able to continue creating rules manually, I'm wondering if there's some sort of management interface we could use to create the rules quickly and easily. We're looking to be able to save time working on our firewall as well as providing a simple method for modifying rules for those who will eventually replace us. I know webmin (heavily locked down on our network, naturally) has support for modifying iptables rules, but seemingly no support for ip6tables. Something similar would be fantastic. Alternatively, suggestions for a firewall solution apart from iptables/ip6tables which can be managed remotely wouldn't be out of order. A web interface for management is certainly preferable, even if it is just a wrapper with shiny buttons over the raw config files.

• x display problems in centos 5.5

  - by John Ruiz

  I have a Dell E510 desktop with a geForce 7200 instead of the ATI x600 it came with. I have attempted to install CentOS 5.4 x86_64 (DVD), CentOS 5.5 (net install), and CentOS 5.5 x86_64 (DVD). Gnome desktop. All of these run into the same issue. When I put the DVD into the machine and reboot, the installer begins and I select "graphical install". I see text that say anaconda is starting, and then my screen goes nuts. It's not black, but rather a screen full of diagonal stripes or multiple colors. So I attempted to do a text install of CentOS 5.5 (DVD) and got it installed. When I booted for the first time, I logged into the virtual console and started X (startx). The desktop came up and it already had the display properties GUI up. I changed it from 800x600 to 1680x1050, saw that there were updates available, installed them, and then rebooted. When I start X from the virtual console this time, I get exactly the same display problem as I described before. Does anyone know what might be causing this and what I can do about it? edit: I should also mention that I'm capable of installing Windows 7 and Ubuntu 10.04 onto this machine with absolutely no issues at all.

• Different network response for indentical co-located machines

  - by Santosh

  We have a situation as follows: We have a two different virtual machines (VMs) on some remote server farm. The machines are identical in terms of hardware/software(OS) configurations. We have a J2EE application running on JBoss on each of those two machines. These two applications are of different version sav V1 on VM1 and V2 on VM2. We observed some degraded response time for application V2 when accessed via public URL. When we accessed the application through a secured VPN, there is hardly any difference. The bandwidth test (upload/download speed, ping etc) shows that VM1 is responding better when accessed via secured VPN. We concluded that the application does not seem to have performance issue. Because, it that's the case the performance degradation should also be there when access via VPN. So we concluded its the network problem. But since those two identical VMs are on same network we are looking for the reasons for different responses. My question is, given the above situation, what could be reasons for such a behavior ?

• SQL Server 2008 second instance times out when logging in -- but only the first time?

  - by Kromey

  This is a strange one that has plagued me for a while now. When logging in to the second instance of SQL Server 2008 on one of our database servers, we get a timeout error: Cannot connect to servername\mssqlserver2. Additional information: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. (Microsoft SQL Server)") (This is the error message when trying to connect with Microsoft SQL Server Management Studio; other tools experience the same error, but of course say it in different ways.) Immediately re-attempting to log in works just fine, so whatever the cause it's ephemeral! This happens regardless of user or authentication type (both Windows and SQL Server authentication methods are supported on this instance). What's even weirder, though, is that the first instance on this server has never once demonstrated this problem. Server is a Windows Server 2008 R2 virtual server, hosted in Microsoft Hyper-V (host is likewise Server 2008 R2). The server has 2GB of RAM, and seems to regularly be using 90% of that -- could low memory be the cause of this issue? I could see this second instance -- which is not used very often yet -- being swapped out to disk, and then taking too long to load back into memory to respond in time to the connection request, but I'd rather have more than just my own hunch before I go scheduling a downtime for this server (the first instance is used regularly) and then just throwing extra resources at it in the blind hope that the problem goes away.

• Value of Itanium over x86_64 for Oracle Deployment

  - by Antitribu

  We are looking at a new environment to run our Oracle Database running on SUSE (potentially migrating to RedHat). Our database is approximately 100GB and performs adequately on our current hardware (x86_64) with approximately 6GB of ram allocated to it. We are growing quickly however and will require more performance shortly. Given the cost of Oracle licenses we would like to maximize the value from each license by choosing the most appropriate CPU to run the software on. The questions are: Are there substantial benefits to looking at Itanium hardware, are there any drawbacks? Is there a point where Itanium starts to scale out better? What are the long term support options for Itanium? Given the dominance of x86 would it be safer long term to stick with x86? On average what would be the performance benefit of implementing an Oracle database on Itanium over x86_64? Is this an issue at all or will other factors (IO/RAM) cap out first? If anyone can point me towards some solid documentation on comparisons between the two platforms that provides good case analysis of when to choose which I'm more than happy to accept that as an answer.

• Using radvd to advertise ipv6 over VPN connection using DD-wrt

  - by Sean Madden

  My ultimate goal is to allow VPN users to have access to my internal IPv6 network from across the intertubes. I've got a linksys WRT54GSv2 running DD-WRTv24SP1 and have configured the little guy as specified here http://www.dd-wrt.com/wiki/index.php/IPv6 and it works wonderfully over the br0 interface (LAN/WLAN bridge). Here's the issue though, when I add an additional interface to the radvd config file on the router (specifically ppp0, for the VPN traffic), radvd refuses to start. The kicker is that on DDWRT, it doesn't give an error message, it just fails outright. Any suggestions on where to proceed from here? /jffs/radvd.conf: interface br0 { AdvSendAdvert on; prefix 0:0:0:1::/64 { AdvOnLink on; AdvAutonomous on; }; }; interface ppp0 { AdvSendAdvert on; prefix 0:0:0:1::/64 { AdvOnLink on; AdvAutonomous on; }; }; The documentation I've found for radvd is slim, but if anyone has a decent idea on how to proceed I'd love to hear it.

• can't backup to a NAS drive as offline schedule task

  - by imageng

  I have seen this problem issue discussed in several forums including this one, but could not find a solution. On MS server 2003 I configured a Backup task, the target backup is on a NAS disc (Seagate BlackArmor NAS 110). The backup task is working well as a scheduled task or by a direct command, when I am logged on. It is not working when the user is offline (in this case - Administrator). I already tried the following actions: 1) addressing to the target as network drive (Y:location..), 2)Using UNC instead, 3) making the drive a domain member (the NAS admin S/W allows to define itself as a domain member) The result log message for 1 and 2 is: "The operation was not performed because the specified media cannot be found." The result log message for 3 is empty file. The schedule task "RUN" command is: C:\WINDOWS\system32\ntbackup.exe backup "@C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\data\de-board.bks" /a /d "Set created 2/14/2010 at 5:10 PM" /v:yes /r:no /rs:no /hc:off /m incremental /j "de-board" /l:s /f "\10.0.0.8\public\Backups\IBMServer\de-board.bkf" 10.0.0.8 is the static IP of the NAS. "Run only if logged on" is NOT marked. Password of the administrator user is set. It is obvious that there is no access to the NAS when the user is logged-out. Do you have any idea how can I solve it? Thanks

• Permissions Required for Sharepoint Backups

  - by Wyatt Barnett

  We are in the process of rolling out an extranet for some of our partners using WSS 3.0 as the platform. We already use it internally for a variety of things, and we are using the following powershell script to backup the server: param( $url="http://localhost", $backupFolder="c:\" ) [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") $site= new-Object Microsoft.SharePoint.SPSite($url) $names=$site.WebApplication.Sites.Names foreach ($name in $names) { $n2 = "" if ($name.Length -eq 0) { $n2="ROOT" } else { $n2 = $name } $tmp=$n2.Replace("/", "_") + ".sbk" $saveas = "" if ($backupFolder.Length -eq 0) { $saveas = $tmp } else { $saveas = join-path -path $backupFolder -childPath $tmp } $site.WebApplication.Sites.Backup($name, $saveas, "true") write-host "$n2 backed up to $saveas." } This script works perfectly on the current installation running as our domain backup user. On the new box, it fails when ran as the backup user--claiming "The web application located at http://extranet/" could not be found. That url does, in fact, work so I'm fairly certain it isn't anything that dumb and rather is some permissions issue. Especially because, when executed from my security context, the script works perfectly. I have tried making the backup user a farm owner, as well as added him to the various site collection admin groups on the extranet. The one major difference between the extranet and the intranet server is that the extranet has an alternative access mapping (for https://xnet.example.com) and also uses forms authentication for that mapping. Anyhow, what permissions (or other voodoo) do I need to setup to get this script to work properly?
