• Looking for suggestions for hosting Windows 2000 Server in the cloud / VPS / etc?

  - by JohnyD

  I have a Windows 2000 Server, currently virtualized in Hyper-V, that I would like to get running off-site as a backup (cloud, VPS, etc). You can't virtualize in EC2 and I'm fairly certain there are no Server 2000 AMI's floating about (correct me if I'm wrong!). If anyone has a recommendation on how I can get a virtualized Windows 2000 Server running in a secure, remote environment I would be grateful. As far as locations go I'd be interested in both North America as well as Australia and Europe. In a nutshell, we're ploughing our way out of a legacy codebase and this server is the last that remains of the legacy apps. However, it is still very much used by our clients. Everything is backed up each night (data, images, etc) to tape which is then taken offsite. However, in the event of a fire I would love to have a backup legacy server to point DNS records to. So while I am rebuilding from the ashes our services would already be available. It would save a lot of time and make my managers all the more happy (and that's what it's all about, riighhtt? :D) Thank you all for your suggestions. Please let me know if I've left out any important information. Additional info: - the legacy codebase does not function properly in Server 2003

• Compressing and copying large files on Windows Server?

  - by Aaron

  I've been having a hard time copying large database backups from the database server to a test box at another site. I'm open to any ideas that would help me get this database moved without having to resort to a USB hard drive and the mail. The database server is running Windows Server 2003 R2 Enterprise, 16 GB of RAM and two quad-core 3.0 GHz Xeon X5450s. Files are SQL Server 2005 backup files between 100 GB and 250 GB. The pipe is not the fastest and SQL Server backup files typically compress down to 10-40% of the original, so it made sense to me to compress the files first. I've tried a number of methods, including: gzip 1.2.4 (UnxUtils) and 1.3.12 (GnuWin) bzip2 1.0.1 (UnxUtils) and 1.0.5 (Cygwin) WinRAR 3.90 7-Zip 4.65 (7za.exe) I've attempted to use WinRAR and 7-Zip options for splitting into multiple segments. 7za.exe has worked well for me for database backups on another server, which has ~50 GB backups. I've also tried splitting the .BAK file first with various utilities and compressing the resulting segments. No joy with that approach either- no matter the tool I've tried, it ends up butting against the size of the file. Especially frustrating is that I've transferred files of similar size on Unix boxes without problems using rsync+ssh. Installing an SSH server is not an option for the situation I'm in, unfortunately. For example, this is how 7-Zip dies: H:\dbatmp>7za.exe a -t7z -v250m -mx3 h:\dbatmp\zip\db-20100419_1228.7z h:\dbatmp\db-20100419_1228.bak 7-Zip (A) 4.65 Copyright (c) 1999-2009 Igor Pavlov 2009-02-03 Scanning Creating archive h:\dbatmp\zip\db-20100419_1228.7z Compressing db-20100419_1228.bak System error: Unspecified error

• Cisco Catalyst 3550 + Alteon 184 Load-Balancing Issues

• Does migrating 2 domain controllers between 2 datacentre requires both virtual machines to be shut down at the same time?

  - by Imagineer

  I was attempting to migrate 2 virtual machines that are domain controllers between 2 datacentres running ESX 3.5 and ESX 4.1. I was advised to shut down both domain controller at the same time during the migration process. This is to avoid USN Rollback and other replication issues. The following are the steps that I was planning to perform: 1. Shutdown both DC. 2. Copy both VMs files across to new datacentre using Veeam FastSCP (connection to both vCentre through IP address instead of hostname) 3. Power them up at new datacentre. 4. Configure Network interface/DNS/DHCP for both DCs in new datacentre I have tried to use Veeam FastSCP rather than VMware Standalone Converter is because its copying rather than converting. Someone also suggested that I use backup and restore app like Veeam backup and replication software. Sounds like a simple job, but after shutting down both DCs, the transfer rate using FastSCP is so slow registering only 1KB/s as oppose to the normal 1MB/s (or more). When that attempt to transfer failed, I tried to cold clone both DCs resulted in the both ESX hosts get disconnected. I have tried troubleshooting by referring to this - VMware KB - Diagnosing an ESX Server that is Disconnected or Not Responding in VirtualCenter It seems that the DNS being down is the caused of all unusual occurrence. The moment I powered up the DCs via VMware console command, the ESX host were able to connect to the vCentre again. How can I avoid such a pitfall again? Am I doing it correctly? Any help would be greatly appreciated! Thank you.

• iTunes copy just metadata (song and album ratings, playlists) from iPod

  - by Jared Updike

  I have an iPod touch that I synched with my Windows computer (iTunes 9.0 I think) until my harddrive failed and I lost my entire library. I rebuilt the library (songs) from a year old backup (and various other source for songs) but my playlists and ratings are of course a year old. My iPod itself has most of the playlists and ratings I care most about (favorite songs and albums, rated 4 and 5, for example). I have a catch 22 situation where I feel nervous that I haven't backed up my iPod in around 4 months (when my drive failed) so I'd like to back it up as soon as possible... but if I back it up I have to clear all the songs and playlists and copy them back, which I can't really do since I need to rebuild my playlists on my computer first (using the data only available on my iPod!) The question: is there a better way to READ the information off my iPod than doing it manually, song by song and album by album and playlist by playlist (XML, text dump, database, spreadsheet, anything). In other words, mostly I want the information (metadata like ratings and playlists, not songs) copied off the iPod so I can more quickly get my iTunes library ratings and playlists re-built (manually) so I can finally wipe the music and back up my apps, etc. Then I'd like to copy the music back immediately. The part I'd like to avoid is manually navigating everything on my iPod to read through all the playlists and ratings (50 GB, 6,000+ songs) as I re-enter all of that data by hand. I've done a few dozen albums and it's pretty time consuming having to tap around on the iPod. Reading from a spreadsheet (for example, or XML which I could write a script to get into spreadsheet form) would probably help tremendously, plus then I'd have a backup of that information somewhere besides just my iPod.

• Track kids browsing history even when they know how to clear it manually

  - by Darren Newton

  I have a colleague with two teenage boys (yes, cue cliche's about 'I have this friend see...') He's currently having issues with them browsing pr0n and wants to do a little spying on their browsing (I'm staying clear of the philosophies/ethics on this.) The kids are savvy enough to clear their browsing history when they're done. As I'm his goto for IT he has asked me if there is a way to keep a hold of the browsing history. The family uses Macs, and the kids surf with Safari. I know that browsing history is kept here ~/Library/Safari/History.plist. I figure there should be a way to write either an AppleScript or other script (Python/Ruby/Bash) that can backup this file to a different location (/opt/local/history, etc.) Since the kids know to clear their history when they're done should the file be periodically backed up with something similar to a cron job or something like Hazel? While that could work it seems like it would create a ton of little incremental backups. Or is it possible to 'watch' ~/Library/Safari/History.plist and incrementally add changes to a backup file (saving a diff so to speak) but not lose any data? Any ideas/solutions appreciated. UPDATE/EDIT: Got the word from concerned dad that the oldest uses Firefox on a different PC, so the OpenDNS solution (preferably at the router level) is the best answer so far as it would capture usage for the whole house.

• What Windows service binds a NIC to the network?

  - by Bigbio2002

  I have a server that takes several minutes for the NIC to bind itself to the network upon startup (it has a statically-configured IP). This causes DNS/WINS/Intersite Messaging to fail to start, since they're dependent on a network connection. While I'm still attempting to find a root cause to this issue (I've done firmware updates, checked for any odd drivers/services, no luck so far), but in the meantime, I want to adjust the load order of services to ensure that the NIC binds first before these services attempt to start. The only question is, which service is it? The server is running Server 2008 R2 and only has one NIC installed. (On a side note, there are two other small but odd problems occuring with the server. The server had the issue described in KB2298620, which I've fixed. The other problem occurs in Windows Server Backup. No events appear in the upper portion of the window, despite the fact that backups are running in the background. Whenever I attempt to modify the backup schedule, it gives me the error "Not enough storage is available to process this command" and appears to fail, when, in fact, it actually succeeds. These may be separate issues, but something tells me that some of these might share a common root cause.)

• While using an ntfs smb share for mac users, do symbolic links and extended attributes work?

  - by scape

  We have a majority of mac users but we'd rather support their file sharing using a Windows server with an ntfs drive, or at least a Linux server with ext3. We've had trouble, much trouble, utilizing the OS X server software and after the years are now looking to abandon it. What's mostly holding us back is the fact that the mac users very often utilize symbolic links and other special features that exist for an HFS+ partition. The shared locations are mostly primary storage and not just used as an archive storage location. While there is an option to create symbolic links under ntfs, I'm curious if there is anything I need to look out for if I were to move the files over to a new partition that's hosted from a Windows server from the HFS+ partition; in addition, how well creating a symbolic link from a mac might work. I am also worried about windows backup software and if it will ruin these special sym links, and how placing permissions on sub-folders will work. Alternatively I could remotely backup the files using a mac and Bru, nonetheless I still want to get away from mac server for hosting the shares.

  Hi, My company have two exchange 2010 SP1 servers with DAG configuration with OS widows server 2008 R2 in testing entironment. Today i want to test my backup possibility, so i restore the backup data to another location not original location. I dismount the database and then delete the all files under the database location. last I copy back the files from back up location to database location. When i want to mount the database. It will come out the below error! -------------------------------------------------------- Microsoft Exchange Error -------------------------------------------------------- Failed to mount database 'mail2'. mail2FailedError: Couldn't mount the database that you specified.

• Files being rolled back on server 2008 R2

  - by Gary

  I've got a weird situation occurring on my dev server. Randomly, and for no reason that I can see, files are being rolled back to an earlier version! This has happened twice now - the first time I assumed I'd done something wrong somewhere, restored the file I was after from a backup and gave it no further thought. The second time, just now, it happened to a folder containing just a few files that I was working on - suddenly all the changes I'd made over the last day or two were gone! (I know, commit more often, ay?). Thankfully I have a daily backup and so have recovered my files, but I'm very concerned about this and need to understand how and why it's happened. The only change made between file states is that I enabled sharing on a completely unrelated folder. I'm developing an app on Railo, which is running on Tomcat. The code was all fine and in c:\websites\appname. I shared the 'Railo' folder, which is c:\railo in order to allow my IDE access to the logs generated by the app (contained in c:\railo\tomcat\logs) and when I reloaded the app, the code was reverted to a few days ago! I'm at a complete loss here. Can anyone point me in the right direction? Thanks.

• Industrial strength cloud file storage

  - by ArthurG

  I'm looking for an industrial strength cloud file storage system. It will be used by multiple people in a startup. Our requirements: Transparent file system access: files and folders in the file system must be able transparently access (read and write) files in the cloud; files must be synchronized whenever network access is available and buffered otherwise. The system must be usable by non-technical people. Access control: we need to control who can access which files, at least on a very coarse basis. e.g., the developers will be able to access the system design documents, only the corporate folks can access recruiting documents, and only management can access certain corporate documents. Dropbox provides this via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. so the cloud service should have a notion of an account (our startup) with multiple users with distinct credentials and rights for each user Clients: it must be accessible from Macs and PCs; I would hope that it supports Linux (e.g., Ubuntu) too Security: it must provide robust security Backup: the cloud service must reliably backup the files Versioning: change version history, is a big plus, but not required Not free: we're willing to pay for the service So far, we've reviewed the following, albeit not completely thoroughly: Dropbox: has all except 1) Access control, which is provided via Sharing folders, but that's not adequate, if I understand it correctly, because there's no authentication of the sharing user. and 2) Security, as discussed here http://www.economist.com/blogs/babbage/2011/05/internet_security and here http://blog.dropbox.com/?p=821. Windows Live Mesh, has all except 1) Clients, only supporting Windows 7 and OS X. SpiderOak has all, except 1) Transparent file system access, which is only available for 1 user. Amazon Cloud, doesn't offer 1) Transparent file system access Rackspace Cloud Drive has all except 1) Access control and 2) Versioning I'll gladly include any clarifications or additional systems the community provides.

• How do I cancel windows server 2003 repair install?

  - by Kilgore2k

  System: Windows 2003 Server Enterprise Scenario: NTDS db is corrupt and all attempts to fix with esentutl fail. Ran chkdsk which seemed to repair disk error and give access to the ntds.dit file but still esentutl fails. (Attached the drive to a different server to run the esentutl) Error: Access to source database '[path to copy of]/ntds.dit' failed with Jet error -1022. Operation terminated with error -1022 (JET_errDiskIO, Disk IO error) after 0.170 seconds. This error occurs on any disk I cpoy the files to including original location in C:\WINDOWS\NTDS\ Now enter the "Stupid!" and "what was I thinking!?" part (must be the late hour...) Stupid: No updated backup - after using a backup I get a network password error in the lsass error. what was I thinking!?: Started the install repair from the original CD but the install fails since the AD fails to start. Now I cant boot into any mode (safe mode, AD restore etc) nor complete the repair install. I would really like to avoid a fresh install since I have the Exchange server on this DC and would rather migrate to a new server than have to start from scratch. Thanks!

• System x3550 M2 stuck on system initializing after firmware upgrades

  - by itmanager223

  Hey guys so i have been having this major issue for the last few hours now. I have a system x 3550M2 server and i ran the UEFI and IMM firmware upgrades within windows server 2008 R2 x64. All upgrades went fine and i was told to reboot. I performed the reboot cleanly using the OS restart option. Upon restarting it showed the system initializing screen and it stayed there for a good hour. After that hour i figured it froze and so i powered down and power up again. Now i can not boot back up to even see the IBM splash screen or the OS... I have tried switching the Jumpers to go to the backup UEFI and backup IMM and no luck. I have also reset the CMOS power and i have pressed the reset button 3 times on the light path and no luck. There are no lights light on the light path to indicate anything is broken. The only thing i see on the light path is the number 0.5. Any ideas guys i am quite stumped with this problem. Thanks a lot, Dani Cela

• Ubuntu+Win7--disk error press any key to restart

  - by Siddharth

  Apparently,none of the solutions in any other posts and forums worked for me For some reasons I decided to remove ubuntu from my hard disk drive. My partition table(presently): (/dev/sda1) (fat32) 900 MiB ---(MBR,I suppose) (/dev/sda2) (ntfs) 70 GiB -----(Windows 7) (/dev/sda3) (ntfs) 314.88 GiB --(Personal File storage) (/dev/sda4) (ext4) 80 GiB -----(Ubuntu 13.04) (unallocated) -----1.31 MiB So,after moving(cut-paste) everything(for backup) from the fat32 partition using win7..I booted into Ubuntu and copied the remaining 3 files(hidden in Win7 file explorer) --bootmgr,bootsect.bak,and one more which I do not remember.TERRIBLE MISTAKE After this I again booted into Windows and deleted ext4 partition..formatted it to ntfs..and shut down the pc.Then,I put in a Win7 bootable USB..using command prompt I entered bootrec /fixmbr,and bootrec /fixboot.. Restarting showed me the GRUB..choosing windows 7 showed me "Disk Error. Press any key to restart." I also installed a fresh Win7 installation on the 80 GiB partition expecting a Windows Legacy Bootloader with two win7 options..but did not work. Then..I used a Ubuntu LiveUSB to put it back to the present configuration(above) since all methods to restore the MBR failed.. I copied back the fat32 partitions backup files but couldn't copy those 3 files.Somehow ,they had been recreated and were non-replaceable. I do not want to format the win7 partition for a fresh one. I have used boot-repair..Restore MBR option brings back to "Disk error...." without even going through grub..so I reinstalled grub and I'm able to boot into Ubuntu. grub menu shows the win7 option as "Windows 7 (loader) (on /dev/sda1)". paste.ubuntu.com/5753710 paste.ubuntu.com/5775999

• Windows 7 - SBS - Why does copying a directory not include all subdirectories and files?

  - by indeed005

  Using Windows 7, fully updated... I have had some strange behaviour copying a whole user directory (e.g. "c:\users\bob" to "c:\backups\bob") I understand now that I should have used Easy Transfer or at least robocopy, but at the time all I wanted to do was backup the user's data before using the "Delete account" button. Unfortunately, I didn't check that my copy-paste had actually worked; all it had actually done was copied the appdata subdirectory of the user account. At the time of doing this backup I was logged in as the same user, bob (a local admin) in this example. When I discovered the missing files, I tried again using the domain admin account -- same story. Only appdata copied. No documents folders, nothing else. Then my boss tried, and it worked fine -- it copied all the files. Ctrl+C, Ctrl+V. I tried again... same profile... copied all the files. Same profile, same destination, same rights and permissions, same ownership, but different behaviour. Has anyone encountered this before and come up with a solution? BTW this was not using roaming profiles and the accounts are stored locally.

• Simple Distributed Disconnected way to sync a directory

  - by Rory

  I want to start regularly backup my home directory on my ubuntu laptop, machine X. Suppose I have access to 2 different remote (linux) servers that I can backup to, machines A & B. Machine X will be the master, and should be synced to A and B. I could just regularly run rsync from X to A and then from X to B. That's all I need. However I'm curious if there's a more bandwidth effecient, and hence faster way to do it. Assuming X is going to be on residential style broadband lines, and since I don't want to soak up the bandwidth, I would limit the transfer from X. A and B will be on all the time, however X, will not be, so I'd also like to reduce the amount of time that X is transfering, potentially allowing A and B to spend more time transfering. Also, X won't be connected all the time. What's the best way to do this? rsync from X to A, then from A to B? Timing that right could be troublesome. I don't want to keep old files around, so if I was to rsync, then the --del option would be used. Could that mean something might get tranfered from A to B, then deleted from B, then transfered from A to B again? That's suboptimal. I know there are fancy distributed filesystems like gluster, but I think that's overkill in this case, and might not fit with the disconnected nature.

• Using Truecrypt to secure mySQL database, any pitfalls?

  - by Saul

  The objective is to secure my database data from server theft, i.e. the server is at a business office location with normal premises lock and burglar alarm, but because the data is personal healthcare data I want to ensure that if the server was stolen the data would be unavailable as encrypted. I'm exploring installing mySQL on a mounted Truecrypt encrypted volume. It all works fine, and when I power off, or just cruelly pull the plug the encrypted drive disappears. This seems a load easier than encrypting data to the database, and I understand that if there is a security hole in the web app , or a user gets physical access to a plugged in server the data is compromised, but as a sanity check , is there any good reason not to do this? @James I'm thinking in a theft scenario, its not going to be powered down nicely and so is likely to crash any DB transactions running. But then if someone steals the server I'm going to need to rely on my off site backup anyway. @tomjedrz, its kind of all sensitive, individual personal and address details linked to medical referrals/records. Would be as bad in our field as losing credit card data, but means that almost everything in the database would need encryption... so figured better to run the whole DB in an encrypted partition. If encrypt data in the tables there's got to be a key somewhere on the server I'm presuming, which seems more of a risk if the box walks. At the moment the app is configured to drop a dump of data (weekly full and then deltas only hourly using rdiff) into a directory also on the Truecrypt disk. I have an off site box running WS_FTP Pro scheduled to connect by FTPs and synch down the backup, again into a Truecrypt mounted partition.

• disk write cache buffer and separate power supply

  - by HugoRune

  Windows has a setting to turn off the write-cache buffer (see image) Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure. Is it feasible and economical to get such a "separate power supply" for the internal sata drives of a non-server PC? Under what name is such a power supply sold? I know that there are UPS devices that can be connected to external drives,but what is required to be able to switch this setting safely on for an internal disk? The setting has different descriptions in different version of windows Windows XP: Enable write caching on the disk This setting enables write caching in Windows to improve disk performance, but a power outage or equipment failure might result in data loss or corruption. Windows Server 2003: Enable write caching on the disk Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows Vista: Enable advanced performance Recommended only for disks with a backup power supply. This setting further improves disk performance, but it also increases the risk of data loss if the disk loses power. Windows 7 and 8: Turn off Windows write-cache buffer flushing on the device To prevent data loss, do not select this check box unless the device has a separate power supply that allows the device to flush its buffer in case of power failure.

• saving data from a failing drive

  - by intuited

  An external 3½" HDD seems to be in danger of failing — it's making ticking sounds when idle. I've acquired a replacement drive, and want to know the best strategy to get the data off of the dubious drive with the best chance of saving as much as possible. There are some directories that are more important than others. However, I'm guessing that picking and choosing directories is going to reduce my chances of saving the whole thing. I would also have to mount it, dump a file listing, and then unmount it in order to be able to effectively prioritize directories. Adding in the fact that it's time-consuming to do this, I'm leaning away from this approach. I've considered just using dd, but I'm not sure how it would handle read errors or other problems that might prevent only certain parts of the data from being rescued, or which could be overcome with some retries, but not so many that they endanger other parts of the drive from being saved. I guess ideally it would do a single pass to get as much as possible and then go back to retry anything that was missed due to errors. Is it possible that copying more slowly — e.g. pausing every x MB/GB — would be better than just running the operation full tilt, for example to avoid any overheating issues? For the "where is your backup" crowd: this actually is my backup drive, but it also contains some non-critical and bulky stuff, like music, that aren't backups, i.e. aren't backed up. The drive has not exhibited any clear signs of failure other than this somewhat ominous sound. I did have to fsck a few errors recently — orphaned inodes, incorrect free blocks/inodes counts, inode bitmap differences, zero dtime on deleted inodes; about 20 errors in all. The filesystem of the partition is ext3.

• Apps won't start after vanilla reboot

  - by Daniel R Hicks

  I had Adobe and Norton nagging me to reboot, so I did that -- clicked Reboot from the Start button. Everything seemed pretty normal as it shut down and came back up, but once up a bunch of apps won't start. The first one I noticed was Firefox. It would flash the disk light normally, but never appear on the screen. Then I tried to bring up an OpenOffice Calc window and same thing. I tried to bring up MS Word, and the splash screen appeared, but never the main screen, and the splash screen just sat there, with a swirly over it. But I tried Solitaire, Notepad++, Paint, and several others, and they popped up just fine. And I'm typing this from IE 8, which, if anything, came up faster than usual. When I try to open up "Network and Sharing Center" the window appears, but nothing appears in it, and eventually it's tagged "not responding". When I kill that window I get (after a delay) "Windows Explorer is not responding", and when I say "OK" the screen resets. I tried rebooting again, and no joy -- same as before. Have done nothing particularly strange on this box, and it's not generally at significant risk for malware. I haven't installed anything new other than the afore-mentioned updates. One other thing: Several minutes after rebooting I get the message "Error: Unable to start Bluetooth Stack Service." The Bluetooth radio is turned on, and I rarely have anything Bluetooth attached, and I don't recall that I've ever seen this message before. Added: Looking at Event Viewer, I'm getting a lot of "The description for Event ID 1 from source xxx cannot be found." Is there any significance to this? Added: I'm looking at restoring from backup, but the procedure is, at best, unclear. Is it sufficient to restore from "Backup and Restore Center", or must I restore from the restore DVD first?

• Can a non-redundant RAID5 cause any serious problems (compared to RAID0)?

  - by leemes

  I used to have a three-disc RAID5 (mdadm) in my computer for personal media storage (music, videos, photos, programs, games, ...). It had three discs with 750 GB each, resulting in an array capacity of 1.5 TB. One day (one year ago), I needed one of those discs to install another operating system. I thought, I don't need the redundancy anymore since I backup the most important stuff (personal photos e.g.) on an external disc anyway. So I decided to remove one of the three discs without converting the RAID to RAID0 or even two separate discs, because I had no temporary storage (since one cannot simply convert the RAID5 to RAID0 AFAIK). So now, for about one year, I have a non-redundant RAID5 with 2 of 3 discs running. Sometimes, one of the discs has a defective contact at the power cable or something similar causing the drive to stop working temporarily (I don't know exactly what it is). Since it still works when rebooting the computer and in most cases by calling some mdadm commands, it wasn't that problematic. Note that the data is not very critical, since I still have a backup of the most important stuff. But in the last few weeks, one of the drives fails very frequently (every few hours), so it gets really annoying to manage this. My questions are: Is there any disadvantage (apart from the annoying management) of a non-redundant RAID5 (with one drive less than typical) over a RAID0? If I understand it correctly, both have no redundancy and the same capacity. On a temporary drive failure, I can restart the array in both cases, assuming that the drive itself still works after the failure. Can it happen that the drive contents alter on a drive failure, making the array inconsistent? If so, can I tell mdadm to check the array for failures (without a file system level checking tool)? Since the drive most probably only has a defective contact causing it to fail for a second only, can I tell mdadm to automatically restart the array, so I will not even notice the failure if no application wanted to access the file system during the failure?

• Restore a database with LDF file only

  - by Martin

  First of all, i know how stupid it is not to have a any backup. I can't help it, but i have to (try) to solve it. I have a transaction log (LDF) file from a SQL Server 2000 database that contains all transactions since the creation of the database. No truncation has been done. The MDF file is gone. Probably because of some disk failure. There is no backup. Not from the original database and not from the transaction log. I have tried to link the transaction log to a new clean database. But (ofcourse) that failed because SQL Server checks the identity of both files. I have read about software that can read the transaction log. ApexSQL seems to do that. I tried to install the trial version but it gives weird errors when trying to start the program. Anyone knows a solution for me? It may contain third party software, but i prefer a clean SQL Server solution.

• Apache with multiple domains, single IP, VirtualHost is catching the wrong traffic

  - by apuschak

  I have a SOAP web service I am providing on a apache web server. There are 6 different clients (IPs) that request data and 3 of them are hitting the wrong domain. I am trying to find a way to log which domain name the requests are coming from. Details: ServerA is the primary ServerB is the backup domain1.com - the domain the web service is on domain2.com - a seperate domain that server seperate content on ServerB ServerA is standalone for now with its own IP and DNS from domain1.com. This works for everyone. ServerB is a backup for the web service, but it already hosts domain2.com. I added entries into the apache configuration file like: <VirtualHost *:443> ServerName domain2.com DocumentRoot /var/www/html/ CustomLog logs/access_log_domain2443 common ErrorLog logs/ssl_error_log_domain2443 LogLevel debug SSLEngine on ... etc SSL directives ... </VirtualHost> I have these for both 80 and 443 for domain1 and domain2 with domain1 being second. The problem is when we switch DNS for domain1 from ServerA to ServerB, 3 out of the 6 clients show up in the debug logs as hitting domain2.com instead of domain1.com and fail their web service request because domain2.com is first in the apache configuration file and catching all requests that don't match other virtualhosts, namely domain1.com. I don't know if they are hitting www.domain1.com, domain1.com (although I added entries for both) or using the external IP address or something else. Is there a way to see which URL they are hitting not just the page request or someother way to see why the first domain is catching traffic meant for the second listed domain? In the meantime, I've put domain1.com higher in the apache configuration than domain2.com. Now it catches the requests for all clients and works, however I don't know what it is catching and would like to make domain2.com the first entry again with a correct entry for domain1.com, for however they are hitting it. Thank you for your help! Andrew

• SBS 2008 Sharepoint Database good Memory Limit.

  - by ldelgado

  I manage a small network running on Small Business Server 2008. Lately, the Sharepoint embedded database is getting out of control with its memory usage. I've got a total of 16 GB of RAM on this server, and the Sharepoint database sometimes uses almost 8 GB of RAM. This never happened before, and it started happening after I installed Backup Exec 2010. It happens after a backup is performed. So I suspect there is a memory leak involved. I am working on that issue, but this question isn't about that. I would like to limit the amount of memory the Embedded database uses. I know how to do it. My question is, what would be the ideal amount of memory that I can allocate to Sharepoint? There are only 4 users on my network. One of the users uses two computers but not at the same time. They use sharepoint for a company calendar, and sometimes they share files that way also. Let me know if you need to know anything else. Thanks,
