• Why does the wireless network icon have a red X over it when everything seems to work?

  - by Kristo

  I booted my almost brand new laptop running Windows 7 this morning and noticed a red X through the wireless networking icon in the system tray. At first I thought something was wrong, but clicking on it shows a good connection to my wireless network. I had no problem getting here to post this question. I'm very new to Windows 7 so I have no idea how to troubleshoot this myself. Is there an actual problem here? Can I fix the icon so it doesn't falsely display an error (I assume that's what the red X means)? Here's what I know: I can get here to post this question. There's at least one unsecured network available that I'm not connected to. I can see a bunch of wireless networks, presumably from my neighbors' houses. There are no other computers turned on in my house right now. The device manager shows no problems with any devices. I can ping my default gateway, DNS, and yahoo.com with no problem.

• Cloning a git repository from a machine running OS X

  - by Mike

  Hi folks, I'm trying to host a git repository from my home OS X machine, and I'm stuck on the last step of cloning the repository from a remote system. Here's what I've done so far: On the OS X (10.6.6) machine (heretofore dubbed the "server") I created a new admin user Logged into the new user's account Installed git Created an empty git repository via "git init" Turned on remote login Set port mapping on my router (airport extreme) to send ssh traffic to the server Added a ".ssh" directory to the user's home directory From the remote machine (also an OS X 10.6.6 machine), I sent that machine's public key to the server using scp and the login credentials of the user created in step 1 To test that the server would use the remote machine's public key, I ssh'd to the server using the username of the user created in step 1 and indeed was able to connect successfully without being asked for a password I installed git on the remote machine From the remote machine I attempted to "git clone ssh://[email protected]:myrepo" (where "user", "my.server.address", and "myrepo" are all replaced by the actual username, server address and repo folder name, respectively) However, every time I try the command in step 11, I get asked to confirm the server's RSA fingerprint, then I'm asked for a password, but the password for the user I set up for that machine never works. Any advice on how to make this work would be greatly appreciated!

• Notify user of message arrival in another mailbox

  - by Tim Alexander

  This is very similar to this question but has a few differences. Basically we have a user dealing with a conflict of interest case. To separate the mail from prying eyes (and the draconian routing system we have in place) the user has been granted access to a second conflicts mailbox that is only accessible to him via OWA. This has worked fine for years but now the user would like a notification to be sent to him when a message arrives in his conflicts mailbox. Initially I thought an Outlook rule would work but of course the client is never logged in so the Outlook rules are never processed. This led me to think that an Exchange Transport rule might work but the only options I can see are to Forward or Copy the message to another user. this would bypass the conflicts setup. All I really need is a notification and not the actual message to be sent. Is this at all possible with Exchange 2007? Or if not is there any thirdparty addition or workaround that anyone has come across?

• Puppet: is it ok to "force" certname when you expect to shuffle nodes around?

  - by Luke404

  We all know (good example on SF) that Puppet hostname detection could be... fun. At our company (and I guess we're not alone at this) we usually pre-configure servers at our offices and test them before bringing the gear to a remote datacenter and rack them. Of course the reverse dns will change when doing that, even if we don't change the actual hostname of the system. We're slowly drafting our puppet setup and I'd like to be sure those moves won't create problems. My idea is to explicitly configure the desired full FQDN of the system as certname in puppet.conf at server provision time (before the very first puppet run). My process would look something like this: basic o.s. installation basic network configuration, enough to reach the internet and resolve dns install puppet and set up certname start puppet and let him manage the whole configuration test, fix problems in config (via puppet), re-test, and so on... manually stop puppet set up new network configuration for the datacenter network move the machine to DC turn it on puppet should automatically start and keep on doing its job The process is supported by detecting the environment in puppet's manifests (eg. based on subnet, like they do at Wikimedia) and modify configuration as needed (eg. resolv.conf contents appropriate for each network). Each node's certname will never change for the whole system life cycle. Is there any problem with this approach? Could it be improved?

• Issues connecting to HP ProCurve switches

  - by BriGuy

  We are having a very strange issue trying to connect to our infrastructure switches via SSH. When you first try connecting to them, the switches will prompt for the password - and then just sit there after it is entered. If you create a second SSH session to the switch (while letting the first one remain open and just sitting there) it will let you log right in. The switches are doing the same thing with RADIUS and local authentication. The other strange part to all of this, is that about 10 switches started doing it all at the same time. As far as actual configuration of the switches, nothing has changed. Occasionally, one switch will start working like normal, but then stop again. These are all HP ProCurve managed switches, but all different models/firmware. Some switches that are not working are using the same firmware as others that are working. UPDATE: 20130312 I am also seeing this same behavior when trying to use telnet. The first telnet session just hangs there, and the second telnet session will let me log in. Rebooting the switches seems to get them working, but I still have 5 production switches that cannot easily be rebooted because of their production roles. Is anyone aware of anything else that can be switched on/off that may reset the logon for remote management or something like that?

• Hyper-V vss-writer not making current copies [migrated]

  - by Martinnj

  I'm using diskshadow to backup live Hyper-V machines on a Windows 2008 server. The backup consists of 3 scripts, the first will create the shadow copies and expose them, the second uses robocopy to copy them to a remote location and the third unexposes the shadow copies again. The first script – the one that runs correctly but fails to do what it's supposed to: # DiskShadow script file to backup VM from a Hyper-V host # First, delete any shadow copies of the drives. System Drives needs to be included. Delete Shadows volume C: Delete Shadows volume D: Delete Shadows volume E: #Ensure that shadow copies will persist after DiskShadow has run set context persistent # make sure the path already exists set verbose on begin backup add volume D: alias VirtualDisk add volume C: alias SystemDrive # verify the "Microsoft Hyper-V VSS Writer" writer will be included in the snapshot # NOTE: The writer GUID is exclusive for this install/machine, must be changed on other machines! writer verify {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} create end backup # Backup is exposed as drive X: make sure your drive letter X is not in use Expose %VirtualDisk% X: Exit The next is just a robocopy and then an unexpose. Now, when I run the above script, I get no errors from it, except that the "BITS" writer has been excluded because none of its components are included. That's okay because I really only need the Hyper-V writer. Also I double checked the GUID for the writer, it's correct. During the time when the Hyper-V writer becomes active, 2 things will happen on the guest machines: The Debian/Linux machine will go to a saved state and restore when done, all fine. The Windows guests will "creating vss snapshop-sets" or something similar. Then X: gets exposed and I can copy the .vhd files over. The problem is, for some reason, the VHD files I get over seems to be old copies, they miss files, users and updates that are on the actual machines. I also tried putting the machines in a saved sate manually, didn't change the outcome. I hope someone here has an idea of how to solve this.

• Configuring two nearby WLANs: should I use the same ssid?

  - by Rory

  I'm configuring a home network for basic internet use (ie don't really need connectivity between workstations on the network). My brick walls mean a single wireless router doesn't provide good coverage throughout the house, so I have purchased two powerline adapters and now have the incoming modem/wireless router at one end of the house plugged into a powerline adapter, and at the other end of the house the other powerline adapter plugged into another wireless router. Currently the two wireless networks have different ssids. (The powerline adapters only do power-Ethernet; they're not wireless access points themselves.) This works well, except when I move between rooms and would ideally like my devices (iPad, phones, laptops) to switch from the weak to the strong signal. Sometimes there's enough signal that they hold on to the weak connects instead of switching to the strong one. Should I name the two networks the same ssid, and if so what is the actual effect? Do the signals get confused, is the bandwidth affected, will this help my devices seamlessly move from one to the other, or is the ssid just a cosmetic thing that actually doesn't have any impact on this situation? Are there any other settings that I should configure to make my setup optimal?

• Can Windows Media Player create playlists based on folder structure?

  - by Chaulky

  Over the years I've carefully molded my digital media collection into a series of folders that make it easy for me to find what I'm looking for. I recently discovered the awesomeness that is streaming video from Windows 7 Media Player to the PS3 so I can watch it on the big screen without all the hassle of hooking the computer up to the TV. The problem is, I totally lose my carefully crafted folder structure and all my videos become one giant mess again... not cool! As a temporary solution, I've created a few playlists for my favorites (Dexter Season 4, Dexter Season 5, Breaking Bad Season 1, etc.). This is a HUGE pain in the a$$. So, is there a way to get Windows Media Player (on Windows 7) to maintain some sort of folder structure based on the location of the actual video files? So if I have my videos sorted into folders by show and season, Media Player will pick that up and let me browse it in the same way. As an alternative answer, I'll accept suggestions for a program that can also stream to PS3 and has this "folder organization" feature.

• How to correctly set GNU Screen to display currently running program in hardstatus

  - by johnny_bgoode

  I posted this question on SuperUser but it's hardly getting any views, so I thought I'd ask here as well. In bash, to display the name of the current program in the GNU Screen hardstatus line takes only two configuration lines. First, tell screen what the end of your prompt normally looks like, and supply a default title for a window when you are sitting at in the shell: shelltitle "$ |bash" Next, place this escape sequence in the PS1 variable, before the characters that normally terminate the prompt '$ ' in this case: \033k\033\\\ This technique works, to a point. The hardstatus window title is updated to the name of the currently running program, and then switches back to the default title shortly after execution is finished. One major problem, however, is that this escape string is not escaped itself, causing line-wrapping problems with commands longer than the initial line. This was annoying, so I set out looking for a solution. Turns out, simply escaping the previous escape sequence corrects line wrapping: [\033k]\[\033\\\] Great! My hardstatus window title still updates to the name of the currently running program, and now my longer commands wrap to the second line correctly. However, with this new escape sequence in my PS1, screen updates the window title to the actual command I am typing, not simply the name of the current program once it is executed. I am wondering, has anyone gotten this working correctly - i.e. line wrapping and proper updating of the hardstatus window title? Thanks!

• Use cell formatting (e.g. "Good", "Bad", "Neutral") in formulas?

  - by ngm

  I am compiling a comparison of different pieces of software in an Excel spreadsheet. It is a big long list of features (the rows), with each column being one of the applications I'm evaluating. I've used styles to visually show how well each product meets each feature, as well as the importance of that feature, and now I'm wondering if there's a way I can use those annotations in a formula. The table is like: . | Product A | Product B | Product C Feature A | blah blah blah Feature B | blah blah blah Feature C | blah blah blah .... | .... | etc | Where I've put 'blah' in the table above, in my actual spreadsheet is (potentially lengthy) descriptive text explaining something about this feature in the given product. I've then used the styles "Good", "Neutral" and "Bad" to visually annotate the description, to show how well each product meets that feature. For each feature I've also used the styles Accent4, 60% Accent4, 40% Accent4, etc, to annotate the importance of each feature. Now I'm wondering if somehow I can use those styles (the annotations) to tot up a total score for each product. e.g., Score for feature A = valueof(60% Accent4) * valueof(Good) Is it possible at all?

• How can one restrict network activity to only the VPN on a Mac and prevent unsecured internet activity?

  - by John

  I'm using Mac OS and connect to a VPN to hide my location and IP (I have the 'send all traffic over VPN connection' box checked in teh Network system pref), I wish to remain anonymous and do not wish to reveal my actual IP, hence the VPN. I have a prefpan called pearportVPN that automatically connects me to my VPN when I get online. The problem is, when I connect to the internet using Airport (or other means) I have a few seconds of unsecured internet connection before my Mac logs onto my VPN. Therefore its only a matter of time before I inadvertently expose my real IP address in the few seconds it takes between when I connect to the internet and when I log onto my VPN. Is there any way I can block any traffic to and from my Mac that does not go through my VPN, so that nothing can connect unless I'm logged onto my VPN? I suspect I would need to find a third party app that would block all traffic except through the Server Address, perhaps Intego Virus Barrier X6 or little snitch, but I'm afraid I'm not sure which is right or how to configure them. Any help would be much appreciated. Thanks!

• Verification of downloaded package with rpm

  - by moooeeeep

  I wanted to install a package on CentOS 6 via rpm (e.g., the current epel-release). EDIT: Of course I would always prefer the installation via yum but somehow I failed to get that specific package installed using this normal approach. As such, the EPEL/FAQ recommends Version 2. As I'm downloading the package through an insecure channel (http) I wanted to make sure that the integrity of the file is verified using information that is not provided with the downloaded file itself. Is this especially true for all of these approaches? I've seen various approaches to this on the internet: Version 1 rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm Version 2 rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm Version 3 wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-7.noarch.rpm rpm --import https://fedoraproject.org/static/0608B895.txt rpm -K epel-release-6-7.noarch.rpm rpm -i epel-release-6-7.noarch.rpm I do not know rpm very well, so I wondered how they might differ? My guess (after reading the manpage) is that the first should only be used when the package is previously not installed, the second would additionally remove previous versions of the package after installation, the first two omit some verification steps before the actual installation that are done by rpm -K. So my main questions at this point are Are my guesses correct or am I missing something? Is the rpm --import ... implicitly done for the first two approaches as well, and if not, isn't it necessary to do so after all? Are these additional checks performed by rpm -K ... any relevant? What is the best (most secure, most reliable, most maintainable, ...) way of installing packages via rpm in general?

• Is there any way to get spotlight or media browser in OSX (Snow Leopard) to index and recognize meta

  - by jaydles

  It seems silly to go to all the trouble to assign "Face" data to thousands of photos, but not make it possible to use that data to locate them outside of that application. I know that that metadata is stored in the "library" database for Aperture/iphoto, rather than on the actual files (which is too bad). And I can even potentially see why it might create challenges for spotlight to use it, since spotlight if presumably a file index system, not a media organizer, but surely the media browser used across the other OSX apps is intended to use it? The media browser's whole purpose seems to be to let you easily locate and reference the items you organize in one of the ilife apps (iphoto or Aperture, in this case) from the others (say, imovie, or Mail). It's particularly vexing since the photo app on the iphone sorts by faces by default. Additionally, the mac-based media browser does access smart albums and folders, so you could establish a workaround by creating a smart album for each "face" or place, or tag, and access them that way, but it seems like there must be an easier way. Am I missing something?

• Free Hosting control panel

  - by John Maxim

  Hello All, I'm in the mid of researching for one of the best hosting control panels. The server I run is Ubuntu and I have some experience with ISPConfig 2 & 3. Since I haven't explored any others available, what are the recommended ones for an Ubuntu server? I asked because I find that there seems to be some disabling and modifications required for an Ubuntu server if I need to use ispconfig which causes the server to change its actual way of running. It's quite good though, but any more recommended ones ? Something more organic? which doesn't require much breaking and changing. I'm not asking for the simple one, I don't mind going extra mile to install a powerful one but just try sticking with most Ubuntu's conventions will be an ideal one for me. And of course, if there happens to be something that meets the requirement as mentioned "Ubuntu conventions" and also simple to install at the same time, that'd be a bonus. Thanks in advance.

• Windows Server wbadmin recover with commas

  - by dlp

  I want to do a recovery of files with commas in their names from the command line, ala: wbadmin start recovery -version:10/01/2013-12:00 -itemType:File -overwite:Overwrite -quiet "-Items:C:\Path\To\File, With Comma.txt,C:\Path\To\File 2, With Comma.txt" So there are two files: C:\Path\To\File, With Comma.txt C:\Path\To\File 2, With Comma.txt The problem is wbadmin assumes commas separates each file, so it sees 4 files specified instead of 2. I've tried putting a \ in front of commas that are part of the file names like so: wbadmin start recovery -version:10/01/2013-12:00 -itemType:File -overwite:Overwrite -quiet "-Items:C:\Path\To\File\, With Comma.txt,C:\Path\To\File 2\, With Comma.txt" but it doesn't work, it just says there's a syntax error. The documentation on Technet doesn't seem to mention anything that'll help either. OS is Windows Server 2008 R2. A clarifying comment: I've changed the file names to be different than the actual names to be less revealing, but I also see I dumbed it down too much. The comma can occur either in the file name itself like C:\Path\To\File, With Comma.txt' or in the path to the file, like:C:\Path, To\Other\File.txt`.

• Take a regular Windows 7 clone with clonezilla (device-to-image)

  - by Mario De Schaepmeester

  I am unexperienced with cloning software and I've decided to use Clonezilla as it seemed best as freeware. I chose device image and left most options standard. I chose expert mode anyway to see what I could configure, and decided to try the lzop algorithm instead of the default one for compression. The rest was left at default. When Clonezilla asked me which partitions to clone (I chose parts to image), I chose the C:\ drive but Windows 7 also creates a 100MB partition on setup for system files (the actual boot partition?). I copied that into the image as well. The reason I didn't choose disk to image is that I also have a data partition that needs to stay intact. Now I'm simply not sure that this is the way to go, should I ever need to restore my disk image. Will Clonezilla know what to do with both partitions and will Windows 7 work perfectly after restoring? Edit: apparantly a similar question has been asked before. The link to the first article in the answer is not relevant to me since it covers a device-to-device clone. It appears the windows installation disk can repair the 100MB partition. As for Clonezilla, it copies "hidden data after the MBR" by default too. I don't know, I feel I'll be allright whether by restoring the partition with Clonezilla or repairing it with the Windows 7 disk.

• Reverse SSH tunnel: how can I send my port number to the server?

  - by Tom

  I have two machines, Client and Server. Client (who is behind a corporate firewall) opens a reverse SSH tunnel to Server, which has a publicly-accessible IP address, using this command: ssh -nNT -R0:localhost:2222 [email protected] In OpenSSH 5.3+, the 0 occurring just after the -R means "pick an available port" rather than explicitly calling for one. The reason I'm doing this is because I don't want to pick a port that's already in use. In truth, there are actually many Clients out there that need to set up similar tunnels. The problem at this point is that the server does not know which Client is which. If we want to connect back to one of these Clients (via localhost) then how do we know which port refers to which client? I'm aware that ssh reports the port number to the command line when used in the above manner. However, I'd also like to use autossh to keep the sessions alive. autossh runs its child process via fork/exec, presumably, so that the output of the actual ssh command is lost in the ether. Furthermore, I can't think of any other way to get the remote port from Client. Thus, I'm wondering if there is a way to determine this port on Server. One idea I have is to somehow use /etc/sshrc, which is supposedly a script that runs for every connection. However, I don't know how one would get the pertinent information here (perhaps the PID of the particular sshd process handling that connection?) I'd love some pointers. Thanks!

• How to resolve 'No internet connectivity issues' with a Virtualised 2008 R2 Server using Forefront UAG

  - by user684589

  I have spent some considerable time reading up on as many possible blogs and articles as I can to help me solve why my VM (Running on Hyper-V) for DirectAccess has suddenly stopped being able to access the internet. The VM setup shares the same internet connection on which I have written and submitted this question so I know that the actual underlying internet connection is fully functional. Previous to last week the DirectAccess was fully functional and had no issues. This is a recent problem which was led up to by a number of consistent crashes on the DA machine when access was attempted. Upon reboot all seemed well until recently. I am not certain whether it is relevant, but previously to this I had a number of power issues where the entire VM host shutdown unexpectedly leaving around 8 VM's in a bad way. Upon restart, the UAG DirectAccess machine was unable to access its configuration service (although the service was started) but this seemed to relate to the Light-Weight Active Directory Service AD LDS which had a corrupted database. Having repaired this database, I restarted the service and could subsequently reconnect to the configuration service again. For good measure I re-bound the network adapters (virtualised through Hyper-V) and DirectAccess claimed to be all happy again. However as it stands my machine is still unable to access the internet showing the "No internet connectivity" exclamation mark for the external facing NIC. I have also tried removing the adapters, disabling, re-enabling and the problem persists. The intranet part of the VM CorpNet seems to be fully functional as before and I'm running out of ideas. Any input would be greatly appreciated. I am not an advanced Domain Administrator so please be gentle.

• Why is MySQL unable to open hosts.allow/hosts.deny?

  - by HonoredMule

  I have a storage server running Nexenta (OpenSolaris kernel, Ubuntu userspace) with MySQL on top of a ZFS storage array, using innodb_file_per_table and ulimit -n set to 8K. mysqltuner.pl confirms the file limit and claims there are 169 files. The following command: pfiles `fuser -c / 2>/dev/null indicates one mysqld process having 485 file/device descriptors (and they're almost all for files) so I don't know how reliable the tuning script is, but it is still way less than 8K and this list also finds no other process which is close to it's limit. The global total number of descriptors in use is around 1K. So what can cause mysqld to be constantly streaming the following errors? [date] [host] mysqld[pid]: warning: cannot open /etc/hosts.allow: Too many open files [date] [host] mysqld[pid]: warning: cannot open /etc/hosts.deny: Too many open files Everything appears to actually be operating fine, but the issue is constantly flooding the admin console and starts right away on a fresh boot (not only reproducible, but always from mysqld and always the hosts files, whose permissions are the default -rw-r--r-- 1 root root). I could, of course, suppress it from the admin console but I'd rather get to the bottom of it and still allow mysqld warnings/errors to reach the admin console. EDIT: not only is the actual file descriptor well within sane limits, the issue also persists (with immediate appearance) even with the file limit raised to 65535 and always only on hosts.allow/deny.

• How do I view source in Outlook 2010?

  - by Martin Duys

  This question has already been asked here; but the answer only gives advice on how to view the email header not the actual html source of the email. There is another question here, which I think may be caused by the same issue as mine, but does not have a satisfactory answer (the answer does not work for the person who posted the question) If I right click on the bottom of an email I can see the option to 'view source' but when I select it nothing happens. I have done a bit of research and came across a post for a much earlier version of Outlook that suggested adding something into the registry. I applied this advice, but it made no difference; but I'm pretty sure that applying this solution correctly for my circumstances will do the trick. When I first received this machine it had a demo version of UltraEdit installed. I uninstalled UltraEdit and installed Notepad++ instead. I am convinced that there is a registry entry that is pointing to UltraEdit as the default view for 'view source' in my email and I need to replace this entry with a reference to Notepad or Notepad++, but I don't know how to do this. Any suggestions?

• How to backup virtual machines on a standalone ESXi host?

  - by Massimo

  Standalone ESXi (4.1) host without any vCenter Server. How to backup virtual machines as quickly and storage-friendly as possible? I know I can access the ESXi console and use the standard Unix cp command, but this has the downfall of copying the whole VMDK files, not only their actually used space; so, for a 30-GB VMDK of which only 1 GB is used, the backup would take 30 full GBs of space, and time accordingly. And yes, I know about thin-provisioned virtual disks, but they tend to behave very badly when physically copied, and/or to blow up to their full provisioned size; also, they are not recommended for actual VM performance. It is ok for me to shut down the VMs before backing them up (i.e. I don't need "live" backups); but I need a way to copy them around efficiently; and yes, a way to automate shutdown/startup when taking a backup would also help. I only have ESXi; no Service Console, no vCenter Server... what's the best way to handle this task? Also, what about restores?

• What is the risk of introducing non standard image machines to a corporate environment

  - by Troy Hunt

  I’m after some feedback from those in the managed desktop or network security space on the risks of introducing machines that are not built on a standard desktop image into a large corporate environment. This particular context relates to the standard corporate image (32 bit Win XP) in a large multi-national not being suitable for a particular segment of users. In short, I’m looking at what hurdles we might come across by proposing the introduction of machines which are built and maintained by a handful of software developers and not based on the corporate desktop image (proposing 64 bit Win 7). I suspect the barriers are primarily around virus definition updates, the rollout of service packs and patches and the compatibility of existing applications with the newer OS. In terms of viruses and software updates, if machines were using common virus protection software with automated updates and using Windows Update for service packs and patches, is there still a viable risk to the corporate environment? For that matter, are large corporate environments normally vulnerable to the introduction of a machine not based on a standard image? I’m trying to get my head around how real the risk of infection and other adverse events are from machines being plugged into the network. There are multiple scenarios outside of just the example above where this might happen (i.e. a vendor plugging in a machine for internet access during a presentation). Would a large corporate network normally be sufficiently hardened against such innocuous activity? I appreciate the theory as to why policies such as standard desktop images exist, I’m just interested in the actual, practical risk and how much a network should be protected by means other than what is managed on individual PCs.

• Moving Images from Database to File System

  - by msarchet

  So currently in our system we have been storing image files in the database (SQL Express 2005). Unfortunately it wasn't perceived that this would reach the max database size allowed by the SQL Express License. So I have proposed a plan of storing the images in the file system and only indexing where the file is in the database. The plan is to save the root path in our OptionsTable as something like ImagesRoot and then only saving the actual imageID in the table, which is basically a FK from the PK of the record with the image. I have determined that it would be best to then split this down into sub-directories inside of the ImagesRoot based on every 1000 images so basically (ImagedID / 1000)\(ImageID % 1000) (e.g. ImageID is 1999 it would be in %ImageRoot%\1\999). I'm looking for any potential pitfalls of this system and any thing that could be improved as I am already receiving some resistance from the owner of the company who wants everything to be in databases. Along those lines I would also take reasons why it should all be in databases. I should mention we have in place already automated backups that run for all of our customers databases and any files that are generated by our program that are required to be saved over a period of time These are optional but if someone isn't using our system it is expected that they are using their own or data loss isn't our problem (it is if our system fails and they are using it!). Thanks
