• Using our own certificate authority for business email encryption

  - by LumenAlbum

  I've read the available similar questions on serverfault but I haven't quite found a definite answer to the security aspect of it - hence here's my question: I'm administrator of an office working with tax data and we want to start using certificate-based eMail encryption with our clients. Considering the prices for issued certificates by VeriSign & Co I was wondering if we couldn't issue the necessary certificates with a certificate authority of our own. I realize that they do not offer the trust hierarchy that commercial certificates do but I don't see why we would need that. Most of our clients have small businesses and only 20% of them even exchange data with us via email. So if we were to issue certificates for those 20% and our employees, that would enable us to use encrypted emails. Of course they would have to trust our certificate authority and thus once receive our public root certificate. But if we would hand them out to them (or install it) personally, they'd know that it really is our certificate. Is thery a huge security risk that I am missing here? As long as nobody has access to our certificate authority server nobody should be able to interfere with security, right? And the client certificates would be generated and handed out by us, as well... Please advise me if I am making an error in judgement here and thank you in advance.

• Connection error when trying to browse SSAS cube in BIDS

  - by lance

  SQL Server 2008 db instance is installed on a win 2003 server, networked (but no domain) VM. I can browse a cube from BIDS on the same VM, but when I try to browse the same cube on a windows 7 (home premium) networked machine, I get a connection error. The error suggests checking the datasource settings which I have, and when I click "test connection" on the datasource it is successful. Looking for probably causes and solutions?

• Beginners advice on Small business network disk(s)

  - by Rob

  We are having 10 PCs used by various user and presently use one network disk (a LaCie NAS) for all our data. Everything is Windows Vista and our collective IT hardware knowledge is minimal. This worked well generally. However, recently the disk freqently loses connection from the network (2-3 times per week) and the only way back seems to be the "turn it off and back on" trick. This obviously cant be any good for the disk. I understand that there are various more sophisticated ways of storing data and was wondering what people would recommend. One of the worries is obviously disk failure (either in part or as a whole) and the lack of continued availability due to network issues. I would guess that a disk which replicates data wouldnt work as a sole solution due to the network connection, but dont know what hardware (and/or software) would/could work in our case. In terms of size, we are looking at very small amounts, ie. less than 500 GB in total.

• Fax in Small Business Server 2003 fails to hang up

  - by Tim Anderson

  We have a problem with fax in SBS 2003. External modem, Courier v Everything which is a recommended model. It receives a fax OK, but then sometimes (quite often) fails to hang up. Attempts to send faxes thereafter get an engaged tone. The only fix when this happens is to reset the fax modem. Even restarting the server is not enough. We've tried with a different model modem, same problem. Any ideas? Tim

• Can't change user security on folder - Business Objects XI 3.1

  - by Chris W

  I've got a single folder within the list of All Folders that I can't change any user permissions on. I'm logged in as an admin and when I view security for the folder it says I have full rights to the folder yet i can't change anything on it or it's sub folders even though it clearly shows me as having rights to "Modify the rights users have to objects". As a test I added a new sub-folder called Test which created ok but I'm not able to then delete the sub folder or change it's permissions either. Interestingly we changed permissions on one sub-folder last week without issue but when I check that folder today I now can't update it. Any ideas anyone?

• Small business VPN solution

  - by Crash893

  I've been looking for a while but I'd like to to implement a vpn solution for anywhere from 1-5 employees at a time (possibly 10 in a year or so) edit: Basically I would like outside users to fire up a client or open a web page and be able to access things inside the company network (share drives / printers/ webapps /etc) I've looked at Astaro Gateway but im not sure if that's the right tool for the job. I know "best" is a subjective term so i would like to break it into to different suggestions 1) what is the cheapest solution given the criteria above 2) what solution will result in the least amount of headaches from the point of view of maintenance and learning curve.

• Suggestions for someone wanting to become a Laptop Reseller

  - by Josh B.

  First of all, to give you a little background... I have had my Microsoft A+ for several years now. I used to run a small business repairing Xbox 360 consoles and I am currently a Network Engineer for a company in Ohio. I definitely know my way around a computer. I miss running a small business on the side and I'd like to get something going again. There is a really high demand in my area for Laptops and I was thinking about starting a small Laptop store out of my house. What is the best way to do this? I was assuming that the best way would be to buy barebones systems and build them yourself. If this is the best method, I would be very interested in any resources to get parts and such. Apparently Laptop parts aren't the easiest thing to come by (especially at a good price). Does anyone have any suggestions about how to get something like this going?

• Locked out of our Comcast Business Gateway for seemingly no reason

  - by Tyler

  A little backstory... Last fall we migrated our ISP from AT&T to Comcast at one of our offices. At that time, we received a new modem/router from Comcast and we configured everything to our liking. We've never really had very many issues with the router aside from having to restart it every once in a while. Here's the problem... About three months ago I changed the password on the router from the default. After that, I logged into the router several times to make changes with no issue. During May I logged into the router to add two new static routes, no problems. A week ago, I tried to log into the router and could not. I tried the non-default password that I changed it to, the default, anything and everything I could think of and no luck. I restarted the router on Monday thinking it may just be locked up, but after the restart it would still not let me log in. This router is at our other office about 2 hours from here and I want to avoid having to drive down there and reset to factory defaults, reconfigure, etc. Any ideas?

• Converting an Small Business Server to a Workstation

  - by noway

  I am planning to buy a Dell PowerEdge T110 Server and convert it to workstation similar to Dell PowerEdge Precision T1700. The reasoning behind is the cost, if I do it by myself, it costs two times cheaper. However, I wonder what might go wrong in this way? The things I have thought of are: Client OSes are not officially supported. There might be some driver problems. The chasis is designed to be a server case, so there are not many useful inputs in the front side of the case. The server boots slower than usual PCs. What might else be a problem?

• Migrate active directory to Google apps for business

  - by dewnix

  I've got a problem migrating active directory to Gapps. I'm stuck on google apps directory sync (GADS) where it just gives the error "java.lang.NullPointerException" after testing the connection during the LDAP configuration step. I checked the logs and I've pretty much determined that port 389 (standard LDAP port) isn't listening on the exchange server. I've tried telneting to it (from another machine in the same network) with no luck but I can telnet to other ports, that i know are open, successfully. I know they're open because I used portqry and netstat to see them. I'm suspecting that the active directory isn't even installed/running on this machine because there's no active directory services at all running on it. There's no active directory services that say they're NOT running either though. Is it possible AD is installed somewhere else? does it have to be on a machine inside the same network? I found the domain controller and it's host name and when I telnet with port 389, it works however GADS still gives me the same exact error when I substitute that server in. Actually, no matter what ridiculous settings i put into GADS, i still get that same NullPointer error. If i could get some different error than that NullPointer, i'd call that a successful day.

• Small Business Server 2011 and Remote access to documents

  - by Tim Long

  Assume I'm working away from the office; its a hotel computer Windows 7, Office 2010 and fast - so the best possible conditions. Using Companyweb - Every time I open a document, I have to go through the logon process - seems odd to have to do that. Is this a 'by design' feature or is something wrong with my configuration? When I do open the documents, are they being stored somewhere locally and should I be looking to delete on this computer - or are they in a temporary file?

• OSX : Setup for filestorage in medium business

  - by Franatique

  In our office every machine runs OSX. In search of an ideal storage and sharing solution we decided to let OSX Server handle all account information and auth requests whereas an 7TB QNAP provides NFS shares. All shares are published as mounts in the companywide LDAP. As it turns out, handling permissions in this situation is very clumsy (e.g. inherit permissions on newly created files). Unfortunately using NFS4 in combination with ACLs did not solve the problem. As a possible solution I set up a iSCSI connection between QNAP and the machine running OSX Server which in turn serves the LUN as AFP share. Permission handling works like a charm for this setup. Although I am a bit concerned about the performance of this setup. As we are a fast growing company we expect the solution to serve at least 100 clients while using files aprox. above 100MB each. Are there any known drawbacks of this solution?

• Server spec for a small business [duplicate]

  - by I'll-Be-Back

  This question already has an answer here: Can you help me with my capacity planning? 2 answers I will need to buy a decent server for Windows Server 2012 and Linux for Web server (Internal use only - Intranet). I will install ESXi with 2 or 3 VM's. There will be about 80-100 Agents at work, they will login (domain controller) on client PC in the morning (between 9:40am to 10:05am). They can only use IE browser and everything else will be locked. They will not have any storage space, no email, etc. Is this spec decent enough? 2u Supermicro 825 chassis, X9SCL-F x1 Intel E3-1290v2 16Gb DDR3 x2 Intel 520 Series 240Gb x2 2Tb Seagate Barracuda, LSi 4 port SAS raid controller

• SAN for Medium Business - Where to start? [closed]

  - by Henson

  I've always run Linux on my home computers, and done PC repair for years, but this is my first experience with needing to buy a SAN. I thought I was knowledgeable, but I feel a bit lost. I need to be able to support 25 VMs, which are currently managed through vSphere. The company I'm at is growing quickly though, so I'd like to plan for the future. Ideally, I want a solution that I can just tack arrays onto and manage as one large, iSCSI drive. Suggestions? Good resources? If I can find something that appears to software as one large drive, am I better off going with a solution like FreeNAS or Starwind, or an all-in-one proprietary solution like NetApp? Cost, is (of course, and always I'm sure) an issue.

• is Drupal good business POS [on hold]

  - by mavili

  I've got to work on a POS-type web application for a money transfer, shipping, and other customer services like translation and help-out charges. I was planning to do that in pure PHP without frameworks or CMS's, but then Drupal came into play and I'm wondering if I should learn Drupal and do the app with it. My question is, is Drupal good for such a work, and if it is will it take me more than a week to learn enough to make it possible? For info, I'm a decent PHP programmer.

• Applying business logic to form elements in ASP.NET MVC

  - by Brettski

  I am looking for best practices in applying business logic to form elements in an ASP.NET MVC application. I assume the concepts would apply to most MVC patterns. The goal is to have all the business logic stem from the same place. I have a basic form with four elements: Textbox: for entering data Checkbox: for staff approval Checkbox: for client approval Button: for submitting form The textbox and two check boxes are fields in a database accessed using LINQ to SQL. What I want to do is put logic around the check boxes on who can check them and when. True table (little silly but it's an example): when checked || may check Staff || may check Client Staff | Client || Staff | Client || Staff | Client 0 0 || 1 0 0 1 0 1 || 0 0 0 1 1 0 || 1 0 0 1 1 1 || 0 0 0 1 There are to security roles, staff and client; a person's role determines who they are, the roles are maintained in the database alone with current state of the check boxes. So I can simply store the users roll in the view class and enable and disable check boxes based on their role, but this doesn't seem proper. That is putting logic in UI to control of which actions can be taken. How do I get most of this control down into the model? I mean I need to control which check boxes are enabled and then check the results in the model when the form is posted, so it seems the best place for it to originate. I am looking for a good approach to constructing this, something to follow as I build the application. If you know of some great references which explain these best practices that is really appreciated too.

• A business Case for Enterprise Python

  - by Srirangan

  Hi all, This will not be a "programming" question but more technology / platform related question. I'm trying to figure out whether Python can be a suitable Java alternative for enterprise / web applications. Which are the ideal cases where you would prefer to use Python instead of Java? How would a typical Python web application (databases/sessions/concurrency) perform as compared to a typical Java application? How do specific Python frameworks square up against Java based frameworks (Spring, SEAM, Grails etc.)? For businesses, switching from the Java infrastructure to a Python infrastructure .. is it too hard/expensive/resource intensive/not viable? Also shed some light on the business case for providing a Python + Google AppEngine based solution to the end customer. Will it be cost effective in an typical scenario? Sorry if I am asking too wide a question, I would have liked to keep it specific, but I need your help to evaluate Python as a whole from the perspectives of the programmers, service providing company and end business customer. For an SME, a Python/GoogleAppEngine based technology stack is a clear scalable and affordable platform. But what about a large MNC that already has a lot invested in Java. Thank you so much. I am researching this myself and will gladly share my conclusions here! Thank you, Srirangan

• Sharepoint BDC Error: The title property of entity tblStaff is set to an invalid value

  - by Christopher Rathermel

  I am just starting to create our Business Data Catalog(s) for our practice management system and I am running into an issue w/ our staff table. Background: I am using Business Data Catalog Definition Editor to create my ADF. I am using the RevertToSelf Authentication Mode. I have tried a few other tables and they seem to work just fine thus far.. only issue is w/ the staff table. If I removed all the columns for the staff entity except the ID and a few columns for the name it actually works. So it has a problem w/ one of my columns in tblStaff. I receive this error even when I set up an ADF w/ just this one entity. So w/ no associations.. When attempting to view the record: http://servername/ssp/admin/Content/tblstaff.aspx?StaffID={0} w/ {0} replaced w/ an actual staff ID I get the following error: The title property of entity tblStaff is set to an invalid value. Things I have tried: I noticed that I do have a column in my staff table called "Title" and removed it from ADF w/ no luck... Same error.. I tried to use bdc meta man to create my ADF and I got the same error... Any ideas? Chris

• Should DAL always return business objects in MVP

  - by Chathuranga

  In Model View Presenter (MVP) pattern, it is said that our DAL always should returns business models. But let's say if I want to get just a number from database like the last ClientID (the latest clients ID) which is a string, should my DAL method returns a ClientInfo object which has about 10 other fields as well like ClientName, Address etc.? If I want to get a list of business objects from my DAL, is it acceptable to do it as follows or better to get a DataTable from DAL and then in the applications BLL, converts it a List? public List<Employee> GetNewEmployees() { string selectStatement = "SELECT Employee.Emp_ID, Employee.Initials + ' ' + Employee.Surname AS Name,..."; using (SqlConnection sqlConnection = new SqlConnection(db.GetConnectionString)) { using (SqlCommand sqlCommand = new SqlCommand(selectStatement, sqlConnection)) { sqlConnection.Open(); using (SqlDataReader dataReader = sqlCommand.ExecuteReader()) { List<Employee> list = new List<Employee>(); while (dataReader.Read()) { list.Add ( new EpfEtfMaster { EmployeeID = (int) dataReader ["emp_id"], EmployeeName = (string) dataReader ["Name"], AppointmentDate = (DateTime) dataReader["appointment_date"], }); } return list; } } } }

• how do I best create a set of list classes to match my business objects

  - by ken-forslund

  I'm a bit fuzzy on the best way to solve the problem of needing a list for each of my business objects that implements some overridden functions. Here's the setup: I have a baseObject that sets up database, and has its proper Dispose() method All my other business objects inherit from it, and if necessary, override Dispose() Some of these classes also contain arrays (lists) of other objects. So I create a class that holds a List of these. I'm aware I could just use the generic List, but that doesn't let me add extra features like Dispose() so it will loop through and clean up. So if I had objects called User, Project and Schedule, I would create UserList, ProjectList, ScheduleList. In the past, I have simply had these inherit from List< with the appropriate class named and then written the pile of common functions I wanted it to have, like Dispose(). this meant I would verify by hand, that each of these List classes had the same set of methods. Some of these classes had pretty simple versions of these methods that could have been inherited from a base list class. I could write an interface, to force me to ensure that each of my List classes has the same functions, but interfaces don't let me write common base functions that SOME of the lists might override. I had tried to write a baseObjectList that inherited from List, and then make my other Lists inherit from that, but there are issues with that (which is really why I came here). One of which was trying to use the Find() method with a predicate. I've simplified the problem down to just a discussion of Dispose() method on the list that loops through and disposes its contents, but in reality, I have several other common functions that I want all my lists to have. What's the best practice to solve this organizational matter?
