I created an RDS instance with SQL Server Express Edition on it. The instance setup was all fine, and I also succeeded connecting to it.

But once connected using the master user, I cannot create any database, schema or table on the server. It keeps saying that the user does not have permission to perform the operation.

What could I be missing? Shouldn't the master user be having all the privileges by default? If not, how should I proceed?

Thanks for any help!

Edit:

This is what I'm trying to run:

CREATE TABLE [dbo].[wt_category] (
    [sys_id] bigint NOT NULL IDENTITY(1,1) ,
    [sys_timestamp] timestamp NOT NULL ,
    [country] varchar(5) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
    [days] date NOT NULL ,
    [pages] varchar(255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL DEFAULT NULL ,
    [visits] int NULL DEFAULT NULL ,
    [page_impressions] int NULL DEFAULT NULL ,
    [visits_w_product] int NULL DEFAULT NULL ,
    [products] varchar(255) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
    PRIMARY KEY ([sys_id])
)

and I get this error:

[Err] 42000 - [SQL Server]CREATE TABLE permission denied in database 'rdsadmin'.

While sending a large file to a Zebra Printer on the network (connected over wireless), the PHP script is throwing an error saying:

PHP Notice: fwrite(): send of 5932 bytes failed with errno=10054 An existing connection was forcibly closed by the remote host.

The printer has an internal print server and I have access to its settings.

I am trying to figure out how to solve this, but got no clue.
Anyone could help me please? Thank you.

I am new to any kind of virtualization and seeking some help here.

I want to install some 15 terminals in my industrial plant, which will control job workflow and monitors the part movement in the factory. Our online workflow application runs on nothing but a Chrome browser, which is the only application the client machines need to access. Instead of going for isolated setup, my friend suggested to go for a virtual setup, so OS maintenance becomes easier and client downtime can be handled easily.

How should I go about this? The only option I am aware of is the Citrix XenDesktop, but the license is bit expensive for our 'browser-only' need.

Do you know of any cheaper solution which can serve Linux to client computers (which are thin clients) over the network, so people can have access to the browser without running an actual OS locally? Sorry if I sound too lame. As I said, I am completely new to this.

Thank you for any sort of information.

I want to setup a firewall handling two ISP connections and two routers. For that I am planning to use an old Pentium 3 machine. Now, should I use four network interface cards or a 4-port NIC?

Do both do the same job? Please advice.

I have two routers connected to each other. Both the routers are connected to the WAN using two different ISPs.

Router A is used for the day to day browsing in the office while Router B is connected to a web server that serves pages to public.

When someone from Router A wants to access our website from Router B, the connection is getting through the WAN. I want to redirect that particular through the LAN instead. Is there any way to do it using the Router A (D-Link DIR-655)?

To summarise, if people in the office want to access pages from 60.51.223.223 (WAN of Router B), the traffic should go through Router B, which resolves the request locally. Router B is a client under Router A.

This is the network map:

We just signed up with a new ISP and we got a static IP from them.

Our previous ISP just gave one IP and we were able to configure our web server using that. Now, we have got this new IP with a slash notation. This type is new to me. When I used the CIDR calculator, it gave me the following results:

    202.184.7.52/30
    IP: 202.184.7.52
    Netmask: 255.255.255.252
    Number of hosts: 2
    Network address: 202.184.7.52
    Broadcast address: 202.184.7.55

Can someone please help me by explaining what these are? I could not understand what the number of hosts means. Is that telling that I can use two different IP for DNS (A) records? Also, which one should I setup in my router? The network address or broadcast address?

Thank you very much for any answer you may provide.
